It&#8217;s the physical embodiment of a drinking philosophy \u2014 the Japanese belief that <em>how<\/em> you serve sake matters as much as which sake you serve. In a culture where the act of pouring for someone else is an expression of care and respect, the vessel that mediates that act carries real significance.<br \/>\n<div class=\"expert-box\"><div class=\"expert-box__photo\"><img decoding=\"async\" src=\"https:\/\/kanpai-navi.com\/wp-content\/uploads\/2026\/02\/IMG_9981.jpg\" alt=\"Daichi Takemoto\" \/><\/div><div class=\"expert-box__info\"><p class=\"expert-box__label\">Supervised by<\/p><p class=\"expert-box__name\">Daichi Takemoto<\/p><p class=\"expert-box__role\">Authentic Bartender &amp; Owner of Obanzai Nanchatte, Kobe<\/p><p class=\"expert-box__bio\">With 8 years of experience as a professional bartender and now the owner of \"Obanzai Nanchatte\" in Kobe, Daichi brings hands-on expertise in Japanese sake, whisky, and food pairing to every article on Kanpai Navi.<\/p><\/div><\/div><\/p>\n<h2 id=\"what-is-a-tokkuri\">What Is a Tokkuri?<\/h2>\n<p>A tokkuri is a traditional Japanese flask designed specifically for serving sake. Its defining feature \u2014 a wide, bulbous body that tapers to a narrow neck \u2014 is a piece of functional engineering that solves multiple problems simultaneously: heat retention, pour control, volume management, and aesthetic presentation.<\/p>\n<p>The name &#8220;tokkuri&#8221; likely derives from the sound sake makes when poured from the flask \u2014 a rhythmic &#8220;tokku, tokku&#8221; as air enters the narrow neck to replace the departing liquid. Some etymologists trace it to the Korean word &#8220;tokkuri&#8221; for a similar vessel, reflecting the deep historical exchange between Japanese and Korean ceramic traditions.<\/p>\n<table>\n<thead>\n<tr>\n<th>Feature<\/th>\n<th>Detail<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Japanese<\/strong><\/td>\n<td>\u5fb3\u5229 (tokkuri, also written tokuri)<\/td>\n<\/tr>\n<tr>\n<td><strong>Function<\/strong><\/td>\n<td>Sake serving and warming flask<\/td>\n<\/tr>\n<tr>\n<td><strong>Standard sizes<\/strong><\/td>\n<td>1-go (180ml), 2-go (360ml), 3-go (540ml)<\/td>\n<\/tr>\n<tr>\n<td><strong>Primary materials<\/strong><\/td>\n<td>Ceramic, porcelain, glass, tin<\/td>\n<\/tr>\n<tr>\n<td><strong>Paired with<\/strong><\/td>\n<td><a href=\"\/en\/drinkware\/sake-cup\/\">Ochoko<\/a> (small cups) or guinomi (larger cups)<\/td>\n<\/tr>\n<tr>\n<td><strong>Price range<\/strong><\/td>\n<td>$10-200+ (everyday to artisan)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"the-physics-of-warming\">The Physics of the Tokkuri: Why Shape Matters<\/h2>\n<p>The tokkuri&#8217;s shape isn&#8217;t traditional for tradition&#8217;s sake \u2014 it&#8217;s an engineering solution for the specific challenge of serving temperature-sensitive sake. Understanding the physics helps you choose the right tokkuri and use it effectively.<\/p>\n<h3>The Narrow Neck: Heat Retention<\/h3>\n<p>Heat escapes a liquid container primarily through evaporation from the surface. The tokkuri&#8217;s narrow neck creates a tiny opening \u2014 typically 2-3cm in diameter \u2014 that dramatically reduces the surface area exposed to air. A standard 2-go tokkuri with a 2.5cm neck opening exposes roughly 5cm\u00b2 of sake to the atmosphere. The same 360ml of sake in an open bowl would expose 80-100cm\u00b2. This means the tokkuri retains heat approximately 15-20 times more effectively than a wide-mouthed vessel.<\/p>\n<p>The narrow neck also creates a &#8220;plug&#8221; of warm, humid air above the sake surface that further reduces evaporative heat loss. This is why <a href=\"\/en\/sake\/hot-sake\/\">warm sake<\/a> served in a tokkuri stays at its target temperature for 15-20 minutes, while the same sake in a bowl cools noticeably within 5 minutes.<\/p>\n<h3>The Wide Body: Even Heating<\/h3>\n<p>When you place a tokkuri in a hot water bath (the traditional warming method), the wide body maximizes the surface area in contact with the heating water. The thin walls of the ceramic conduct heat inward, and the sake circulates naturally through convection \u2014 warm sake rises from the walls, cooler sake descends from the center, creating gentle circulation that heats the entire volume evenly.<\/p>\n<p>This is crucial because sake is extremely sensitive to uneven heating. A microwave creates hot spots where localized overheating can destroy delicate aromatics while other areas remain cold. The tokkuri-in-water-bath method heats the sake uniformly, ensuring every sip is at the same temperature.<\/p>\n<h3>The Pour: Precision and Ritual<\/h3>\n<p>The tapered neck funnels sake into a controlled, elegant stream \u2014 essential when pouring into ochoko cups that hold only 30-60ml. A wide-mouthed vessel would produce an uncontrollable splash. The tokkuri&#8217;s neck also prevents over-pouring \u2014 the natural flow rate from the narrow opening matches the small cup size perfectly.<\/p>\n<p>The ritual significance is real: in Japanese drinking culture, pouring sake for someone else (oshaku) is an act of hospitality and care. The tokkuri makes this gesture graceful rather than awkward. The one-handed pour, the gentle tilt, the &#8220;tokku tokku&#8221; sound \u2014 these are the sensory elements that elevate sake service from functional to ceremonial.<br \/>\n<div class=\"expert-bubble\"><div class=\"expert-bubble__avatar\"><img decoding=\"async\" src=\"https:\/\/kanpai-navi.com\/wp-content\/uploads\/2026\/02\/IMG_9981.jpg\" alt=\"Daichi Takemoto\" \/><\/div><div class=\"expert-bubble__body\"><p class=\"expert-bubble__name\">Daichi Takemoto<\/p><p class=\"expert-bubble__text\">I own about thirty tokkuri \u2014 from \u00a5500 flea market finds to a \u00a530,000 Bizen piece I bought directly from a potter. The expensive ones aren&#8217;t &#8220;better&#8221; at holding sake. What changes is how the experience feels \u2014 the weight in your hand, the texture of the clay, the way it ages with use. A good tokkuri develops a patina over years of use that becomes part of its beauty. My most-used tokkuri is a simple brown Shigaraki piece I bought ten years ago. It&#8217;s the one that feels like home.<\/p><\/div><\/div><\/p>\n<h2 id=\"regional-pottery-guide\">A Guide to Japanese Pottery Traditions<\/h2>\n<p>One of the most rewarding aspects of choosing a tokkuri is discovering Japan&#8217;s regional pottery traditions. Each tradition has a distinct aesthetic, a specific type of clay, and different functional properties that affect how the tokkuri interacts with sake. This isn&#8217;t just art history \u2014 the material genuinely changes the drinking experience.<\/p>\n<h3>Bizen-yaki (\u5099\u524d\u713c) \u2014 Okayama<\/h3>\n<p>Japan&#8217;s oldest pottery tradition, with 1,000 years of continuous production. Bizen ware is unglazed \u2014 fired at extremely high temperatures (1,200-1,300\u00b0C) for 10-14 days in a wood-fired kiln. The clay naturally vitrifies, creating a dark, earthy surface with distinctive fire marks (hidasuki patterns from straw wrapping, or goma sesame-seed marks from ash deposits).<\/p>\n<p><strong>Sake effect:<\/strong> Bizen&#8217;s iron-rich, porous clay is believed to soften sake&#8217;s rough edges and enhance umami. The microscopic surface texture creates tiny air pockets that increase the sake&#8217;s contact with the clay. Many sake professionals swear that sake tastes smoother and rounder from a Bizen tokkuri. Whether this is chemistry or psychology is debated, but the effect is consistently reported.<\/p>\n<p><strong>Best for:<\/strong> Robust <a href=\"\/en\/sake\/junmai-sake\/\">junmai<\/a> and <a href=\"\/en\/sake\/honjozo-sake\/\">honjozo<\/a> served warm. The rustic aesthetic matches hearty drinking.<\/p>\n<h3>Arita-yaki \/ Imari (\u6709\u7530\u713c) \u2014 Saga<\/h3>\n<p>Japan&#8217;s premier porcelain tradition, producing thin, refined, often elaborately decorated ware. Arita porcelain is fired at very high temperatures, creating a smooth, non-porous surface that&#8217;s easy to clean and doesn&#8217;t affect the sake&#8217;s flavor.<\/p>\n<p><strong>Sake effect:<\/strong> Neutral \u2014 Arita porcelain is inert, so it serves the sake exactly as the brewer intended without adding or subtracting anything. The thin walls transfer temperature quickly, so the sake reaches your lips at the intended serving temperature.<\/p>\n<p><strong>Best for:<\/strong> Premium <a href=\"\/en\/sake\/ginjo-sake\/\">ginjo<\/a> and <a href=\"\/en\/sake\/daiginjo-sake\/\">daiginjo<\/a> where you want to taste the sake itself without any influence from the vessel. Also excellent for formal entertaining \u2014 Arita&#8217;s elegance matches special occasions.<\/p>\n<h3>Shigaraki-yaki (\u4fe1\u697d\u713c) \u2014 Shiga<\/h3>\n<p>Known for its warm, sandy texture and natural, earthy tones. Shigaraki clay is high in feldspar, producing a distinctive pebbly surface that&#8217;s rough to the touch but pleasant to hold. The pottery often has a casual, rustic quality that feels comfortable and unpretentious.<\/p>\n<p><strong>Sake effect:<\/strong> Similar to Bizen but milder. The slightly porous surface may soften sake marginally, and the thick walls provide excellent heat retention for warm service.<\/p>\n<p><strong>Best for:<\/strong> Everyday warm sake. Shigaraki tokkuri are affordable, durable, and have a warmth that makes casual drinking feel natural.<\/p>\n<h3>Tin (\u932b) \u2014 Osaka, Toyama<\/h3>\n<p>Not clay \u2014 tin tokkuri are a separate tradition entirely. Premium tin vessels (from makers like Nousaku in Toyama or Osaka Suzuki) are cast or hammered from pure tin, creating a silvery, metallic surface that&#8217;s beautiful and functional.<\/p>\n<p><strong>Sake effect:<\/strong> Tin has extremely high thermal conductivity \u2014 it heats and cools faster than any ceramic. This makes tin tokkuri ideal for rapid warming and precise temperature control. Some believe tin ions interact with the sake to reduce bitterness and enhance sweetness, though this claim is more folklore than verified chemistry. What&#8217;s undeniable is that the metallic surface creates a different tactile experience \u2014 cold tin in summer is especially pleasant.<\/p>\n<p><strong>Best for:<\/strong> Both warm and chilled sake. The rapid temperature transfer makes tin tokkuri the most responsive to temperature changes, allowing precise control.<\/p>\n<h2 id=\"how-to-warm-sake\">How to Warm Sake in a Tokkuri<\/h2>\n<p>Warming sake properly is a skill with more nuance than most guides acknowledge. The method matters, the temperature matters, and \u2014 critically \u2014 the sake type matters. Here&#8217;s a complete guide.<\/p>\n<h3>The Hot Water Bath Method (Yu-sen)<\/h3>\n<p>This is the traditional and superior method. It heats sake evenly, gradually, and with precise control.<\/p>\n<ol>\n<li><strong>Fill the tokkuri<\/strong> to about 90% capacity. Leave a small air gap at the top \u2014 sake expands slightly when heated, and you want to avoid overflow.<\/li>\n<li><strong>Heat a pot of water<\/strong> to 70-80\u00b0C. This is well below boiling \u2014 you should see small bubbles forming on the pot bottom but no rolling boil. Remove from heat.<\/li>\n<li><strong>Place the tokkuri in the water.<\/strong> The water level should reach approximately the same height as the sake inside. If the water is too shallow, the top portion of sake won&#8217;t warm evenly.<\/li>\n<li><strong>Wait 2-3 minutes<\/strong> for a 1-go (180ml) tokkuri, 3-4 minutes for a 2-go (360ml). The sake will reach approximately 40-45\u00b0C \u2014 the nurukan to joukan range that works for most <a href=\"\/en\/sake\/hot-sake\/\">warm sake<\/a>.<\/li>\n<li><strong>Test with your palm.<\/strong> Touch the bottom of the tokkuri. If it feels warm but not uncomfortable to hold for several seconds, you&#8217;re in the 40-45\u00b0C sweet spot. If it&#8217;s too hot to hold, you&#8217;ve passed 50\u00b0C \u2014 let it cool for 30 seconds.<\/li>\n<\/ol>\n<h3>Temperature Guide for Warm Sake<\/h3>\n<p>Japanese sake culture has named specific temperature ranges, each producing a distinctly different drinking experience:<\/p>\n<table>\n<thead>\n<tr>\n<th>Japanese Name<\/th>\n<th>Temperature<\/th>\n<th>Character<\/th>\n<th>Best Sake Types<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Hinatakan (\u65e5\u5411\u71d7)<\/strong><\/td>\n<td>30\u00b0C<\/td>\n<td>Barely warm \u2014 &#8220;sunshine warm&#8221;<\/td>\n<td>Delicate junmai ginjo (rare \u2014 most are better chilled)<\/td>\n<\/tr>\n<tr>\n<td><strong>Hitohada (\u4eba\u808c\u71d7)<\/strong><\/td>\n<td>35\u00b0C<\/td>\n<td>Body temperature \u2014 soft, gentle<\/td>\n<td>Light junmai, tokubetsu junmai<\/td>\n<\/tr>\n<tr>\n<td><strong>Nurukan (\u306c\u308b\u71d7)<\/strong><\/td>\n<td>40\u00b0C<\/td>\n<td>Comfortably warm \u2014 the sweet spot<\/td>\n<td>Honjozo, junmai \u2014 the most popular range<\/td>\n<\/tr>\n<tr>\n<td><strong>Joukan (\u4e0a\u71d7)<\/strong><\/td>\n<td>45\u00b0C<\/td>\n<td>Warm \u2014 umami emerges fully<\/td>\n<td>Honjozo, robust junmai, kimoto\/yamahai<\/td>\n<\/tr>\n<tr>\n<td><strong>Atsukan (\u71b1\u71d7)<\/strong><\/td>\n<td>50\u00b0C<\/td>\n<td>Hot \u2014 bold, assertive, warming<\/td>\n<td>Hearty junmai, honjozo \u2014 winter drinking<\/td>\n<\/tr>\n<tr>\n<td><strong>Tobikirikan (\u98db\u3073\u304d\u308a\u71d7)<\/strong><\/td>\n<td>55\u00b0C+<\/td>\n<td>Very hot \u2014 intense, sharp<\/td>\n<td>Only the most robust junmai \u2014 for cold weather<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><strong>The critical rule:<\/strong> Never warm <a href=\"\/en\/sake\/ginjo-sake\/\">ginjo<\/a>, <a href=\"\/en\/sake\/daiginjo-sake\/\">daiginjo<\/a>, or nama sake. Heat destroys the volatile aromatic esters (ginjo-ka) that define these styles \u2014 the very compounds you paid a premium for. Warm only <a href=\"\/en\/sake\/junmai-sake\/\">junmai<\/a>, <a href=\"\/en\/sake\/honjozo-sake\/\">honjozo<\/a>, and futsu-shu. These styles gain character from heat; premium aromatic styles lose it.<\/p>\n<h3>The Mistakes That Ruin Warm Sake<\/h3>\n<p><strong>Boiling the water while the tokkuri is in it.<\/strong> This overheats the bottom of the sake while the top stays cool, and the alcohol on the bottom evaporates before the top warms. Always remove the pot from heat before placing the tokkuri in it.<\/p>\n<p><strong>Microwaving.<\/strong> Microwaves create hot spots \u2014 pockets where the sake reaches 60-70\u00b0C while other areas are barely warm. These hot spots destroy aromatics locally. If you must microwave, use 50% power in 20-second intervals, swirling between each. But the water bath method is genuinely better.<\/p>\n<p><strong>Overheating and trying to cool it down.<\/strong> Once sake has been heated past 55\u00b0C, the volatile compounds have evaporated. Cooling it back down doesn&#8217;t restore them. If you overshoot, drink it hot \u2014 it won&#8217;t be ideal, but it&#8217;s not ruined. Next time, aim lower.<\/p>\n<p><strong>Warming too much sake at once.<\/strong> A tokkuri of warm sake should be drunk within 10-15 minutes while it&#8217;s still at its target temperature. Don&#8217;t warm 540ml if you&#8217;ll drink it over an hour \u2014 warm 180ml three times. Fresh pours at the right temperature always beat tepid sake that started hot and cooled.<br \/>\n<div class=\"expert-bubble\"><div class=\"expert-bubble__avatar\"><img decoding=\"async\" src=\"https:\/\/kanpai-navi.com\/wp-content\/uploads\/2026\/02\/IMG_9981.jpg\" alt=\"Daichi Takemoto\" \/><\/div><div class=\"expert-bubble__body\"><p class=\"expert-bubble__name\">Daichi Takemoto<\/p><p class=\"expert-bubble__text\">My warming technique at the bar: I keep a pot of water at 75\u00b0C on a very low flame all evening. When a customer orders warm sake, I fill the tokkuri, place it in the water for 2 minutes 30 seconds (for a 1-go), then touch-test the bottom. I&#8217;ve done this thousands of times, and the touch test is more reliable than any thermometer. Your hand learns what 40\u00b0C feels like. After a few weeks of practice, you&#8217;ll nail the temperature every time without thinking about it.<\/p><\/div><\/div><\/p>\n<h2>Choosing the Right Tokkuri<\/h2>\n<p>The &#8220;best&#8221; tokkuri depends entirely on how you drink sake. Here&#8217;s a decision framework based on real drinking habits rather than abstract ideals.<\/p>\n<h3>If You Drink Warm Sake Most of the Time<\/h3>\n<p>Choose a <strong>thick-walled ceramic tokkuri<\/strong> in the 2-go (360ml) size. Bizen, Shigaraki, or Mashiko ware provide the best heat retention. The thick walls absorb heat slowly and release it slowly, keeping your sake at temperature for 15-20 minutes per fill. Look for a classic bulbous shape with a narrow neck \u2014 the design that&#8217;s been optimized for warm service over centuries. Budget: $20-50 for excellent quality.<\/p>\n<h3>If You Drink Chilled Sake Most of the Time<\/h3>\n<p>Choose a <strong>glass tokkuri or katakuchi<\/strong> (lipped pouring vessel). Glass shows off the sake&#8217;s clarity \u2014 particularly appealing for premium ginjo and daiginjo. A katakuchi&#8217;s wide opening makes it easy to pour and doesn&#8217;t need to retain heat. Some glass tokkuri come with ice pockets \u2014 internal chambers you fill with ice to keep the sake cold without diluting it. Budget: $15-40.<\/p>\n<h3>If You Want One Tokkuri That Does Everything<\/h3>\n<p>A <strong>mid-weight ceramic tokkuri<\/strong> in a neutral glaze (white, grey, or natural clay color) handles warm, room temperature, and chilled service adequately. It won&#8217;t excel at any single temperature the way a specialist vessel would, but it&#8217;s the practical choice for someone who doesn&#8217;t want multiple tokkuri. Budget: $15-30.<\/p>\n<h3>If You&#8217;re Buying a Gift<\/h3>\n<p>A <strong>tokkuri and ochoko set<\/strong> in matched ceramic is the traditional sake gift. Arita or Kutani porcelain sets are elegant and universally appropriate. Look for sets with 2 ochoko cups \u2014 the standard for a couple&#8217;s set. Presentation matters for gifts, so choose a set that comes in a wooden box (paulownia\/kiri-bako). Budget: $30-80.<\/p>\n<h2>Caring for Your Tokkuri<\/h2>\n<p>The narrow neck that makes tokkuri so functional for pouring makes them challenging to clean. Here&#8217;s how to maintain your tokkuri for years of use.<\/p>\n<ul>\n<li><strong>After each use:<\/strong> Fill with warm water immediately and let it sit for 5 minutes. Then rinse thoroughly, swirling water inside to reach the walls. For the narrow neck, a thin bottle brush is essential \u2014 sake residue in the neck can develop off-odors over time.<\/li>\n<li><strong>For unglazed ceramic (Bizen, Shigaraki):<\/strong> Avoid dish soap \u2014 the porous clay absorbs detergent, which can taint future sake. Warm water and a brush are sufficient. If staining occurs, soak overnight in a solution of warm water and baking soda.<\/li>\n<li><strong>For glazed ceramic and porcelain:<\/strong> Mild dish soap is fine \u2014 the glazed surface is non-porous and won&#8217;t absorb anything.<\/li>\n<li><strong>Drying:<\/strong> Air dry completely before storing \u2014 invert the tokkuri on a rack or cloth so water drains from the neck. Never store a damp tokkuri in a closed cabinet; trapped moisture promotes mold growth inside the body.<\/li>\n<li><strong>For tin:<\/strong> Hand wash only with warm water and mild soap. Tin is soft \u2014 never use abrasive cleaners. Polish occasionally with a soft cloth to maintain the luster, or let it develop a natural patina.<\/li>\n<\/ul>\n<h2>Frequently Asked Questions<\/h2>\n<h3>What is a tokkuri used for?<\/h3>\n<p>A tokkuri is a traditional Japanese flask used to serve sake, particularly <a href=\"\/en\/sake\/hot-sake\/\">warm sake<\/a>. Its bulbous body and narrow neck are designed to retain heat, control the pour into small ochoko cups, and create the ritual of Japanese sake service. While primarily associated with warm sake, tokkuri are also used for room temperature and chilled service.<\/p>\n<h3>What size tokkuri should I buy?<\/h3>\n<p>A 2-go (360ml) tokkuri is the most versatile \u2014 it holds enough for two people sharing (about six ochoko pours). For solo drinking, a 1-go (180ml) ensures the sake stays at the correct temperature because you finish it quickly. The 2-go is the standard size in Japanese izakaya and restaurants.<\/p>\n<h3>Can I microwave a tokkuri?<\/h3>\n<p>Most ceramic and porcelain tokkuri are microwave-safe, but the hot water bath method produces superior results. If microwaving, use 50% power in 20-30 second intervals and swirl between rounds. Never microwave metallic-glazed, metal, or lacquered tokkuri.<\/p>\n<h3>What&#8217;s the difference between a tokkuri and a katakuchi?<\/h3>\n<p>A tokkuri has a narrow neck and bulbous body \u2014 optimized for warm sake because the small opening retains heat. A katakuchi is an open-mouthed pouring vessel (like a small pitcher) \u2014 better for chilled sake because the wide opening allows easy pouring and aroma release. Both serve sake; the choice depends on serving temperature.<\/p>\n<h3>Does the tokkuri material affect sake taste?<\/h3>\n<p>Potentially. Porous, unglazed ceramics (Bizen, Shigaraki) are widely believed to soften sake and enhance umami through interaction with the clay&#8217;s minerals. Glazed ceramics and glass are neutral \u2014 they serve the sake without influencing it. Tin is claimed to reduce bitterness, though this is more traditional belief than verified science. The material definitely affects the tactile and aesthetic experience, even if the flavor effect is subtle.<\/p>\n<h2>The Bottom Line<\/h2>\n<p>The tokkuri is where sake service begins \u2014 the vessel that transforms pouring a drink into performing a ritual. Its shape isn&#8217;t decorative; it&#8217;s a centuries-old engineering solution for heat retention, pour control, and communal serving. Choose a thick ceramic tokkuri for warm sake, glass for chilled, and explore Japan&#8217;s regional pottery traditions to find a piece that resonates with your drinking style. A good 2-go ceramic tokkuri with matching ochoko costs $20-40 and will serve you for decades \u2014 developing a patina over years of use that becomes part of its beauty. In a world of disposable drinkware, the tokkuri is a quiet argument for permanence.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What You&#8217;ll Learn in This Article What a tokkuri is \u2014 and why its shape is functional engineering, not decoration The physics of warming sake: &#8230; <a title=\"Tokkuri Guide: How to Choose the Perfect Sake Flask\" class=\"read-more\" href=\"https:\/\/kanpai-navi.com\/en\/drinkware\/tokkuri\/\" aria-label=\"Read more about Tokkuri Guide: How to Choose the Perfect Sake Flask\">Read more<\/a><\/p>\n","protected":false},"author":1,"featured_media":399,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4,17],"tags":[],"class_list":["post-91","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-drinkware","category-tokkuri-sets"],"_links":{"self":[{"href":"https:\/\/kanpai-navi.com\/en\/wp-json\/wp\/v2\/posts\/91","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/kanpai-navi.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/kanpai-navi.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/kanpai-navi.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/kanpai-navi.com\/en\/wp-json\/wp\/v2\/comments?post=91"}],"version-history":[{"count":5,"href":"https:\/\/kanpai-navi.com\/en\/wp-json\/wp\/v2\/posts\/91\/revisions"}],"predecessor-version":[{"id":329,"href":"https:\/\/kanpai-navi.com\/en\/wp-json\/wp\/v2\/posts\/91\/revisions\/329"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/kanpai-navi.com\/en\/wp-json\/wp\/v2\/media\/399"}],"wp:attachment":[{"href":"https:\/\/kanpai-navi.com\/en\/wp-json\/wp\/v2\/media?parent=91"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/kanpai-navi.com\/en\/wp-json\/wp\/v2\/categories?post=91"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/kanpai-navi.com\/en\/wp-json\/wp\/v2\/tags?post=91"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
