If you're coming to Osu for the World Cosplay Summit and you have even a passing interest in rare wagyu, this is the one thing worth knowing before you arrive.

The district has been hosting the World Cosplay Summit for years, and the streets around Osu Kannon Temple have seen everything \u2014 elaborate fantasy armor, anime-accurate wigs, Victorian lolita layers, and everything in between \u2014 without a single raised eyebrow. Costume or no costume, you belong here.<\/p>\n<p>Itadaki sits in the heart of this neighborhood, on the second floor of a building just a four-minute walk from Yabacho Station Exit 4. We have a sofa table that seats five, two tables for four, and counter seats for solo visitors. Whatever your group size, and whatever you're wearing, you're welcome to walk in \u2014 or walk in and sit down. The space is relaxed, the seating is comfortable, and the atmosphere is the kind that lets you focus on what's in front of you: a bowl of wagyu that most people in Japan have never had the chance to eat.<\/p>\n<p>That said, there's one practical concern that comes up again and again from visitors planning their WCS lunch \u2014 and it's worth addressing directly.<\/p>\n<div class=\"sag-cta sag-cta--soft\">\n<p class=\"sag-cta__bridge\">You now know that WCS weekends push Horai Wagyu to sell out faster \u2014 but knowing the schedule before you commit to a day matters just as much. Our monthly business calendar, posted at the start of each month, shows exactly which days we're open so you can plan around it. It takes a moment to check.<\/p>\n<p class=\"sag-cta__action\"><a href=\"https:\/\/www.instagram.com\/itadaki_gyudon.08\/\" target=\"_blank\" rel=\"noopener noreferrer\">Check Itadaki's Monthly Schedule on Instagram<\/a><\/p>\n<\/div>\n<h2>The Real Reason Horai Wagyu Sells Out \u2014 It's Not a Marketing Tactic<\/h2>\n<p>Horai Wagyu is raised in the Okumikawa mountains of Aichi Prefecture. Only three farms in Japan produce it. Only 300 heads are raised annually \u2014 against a total national wagyu population of roughly 500,000. The cattle are fed on sake lees from Horaisen Sora, a locally revered premium sake, which gives the beef a flavor profile unlike any other wagyu: light marbling, clean finish, and a lean depth that's genuinely rare in Japanese beef culture.<\/p>\n<p>Because of this extreme scarcity, Itadaki receives a limited supply each week. We can only offer 10 bowls of Horai Wagyu Rare Gyudon per day. That's not a number chosen for effect \u2014 it's a ceiling set by what the farms can actually provide. On a busy WCS weekend, when Osu is at its most vibrant and visitors are streaming in from across the district, those 10 bowls can be gone within the first hour of service.<\/p>\n<p>This is the core problem for foreign visitors with short Nagoya itineraries. You may have one afternoon in Osu. You may be traveling to Shirakawa-go the following morning. You cannot afford to arrive at 12:30, find the Horai Wagyu sold out, and spend the rest of the afternoon wondering what you missed. The stakes are real, and the solution is straightforward.<\/p>\n<p><strong>\u2713 Key Takeaways<\/strong><\/p>\n<ul>\n<li>Horai Wagyu is limited to 10 bowls per day \u2014 not by policy, but by genuine supply constraints from 3 farms producing only 300 heads annually<\/li>\n<li>WCS weekends are peak hours for Osu foot traffic, which means Horai Wagyu sells out faster than usual<\/li>\n<li>The reservation platform (Tabelog) works in English and takes less than five minutes to use<\/li>\n<\/ul>\n<div class=\"sag-cta sag-cta--mid\">\n<p class=\"sag-cta__bridge\">You've read about the 10-bowl limit and the \u9cf3\u6765\u725b\u5e0c\u671b phrase to paste into the notes field \u2014 now the only step left is actually locking in your date before those bowls are spoken for. Tabelog's reservation form works in English and the whole process takes under five minutes.<\/p>\n<p class=\"sag-cta__action\"><a href=\"https:\/\/yoyaku.tabelog.com\/yoyaku\/net_booking_form\/index?rcd=23081531\" target=\"_blank\" rel=\"noopener noreferrer\">Reserve Your Horai Wagyu Bowl via Tabelog<\/a><\/p>\n<\/div>\n<h2>How to Reserve Horai Wagyu in English \u2014 Step by Step<\/h2>\n<p>Tabelog is Japan's most widely used restaurant reservation and review platform. Outside Japan, it's barely known \u2014 which is exactly why so many foreign visitors skip the reservation step and then arrive to disappointment. Here's how to do it without any Japanese language skills.<\/p>\n<p>Go to the Tabelog reservation page for Itadaki and select your date, time (we're open 11:00\u201315:00 on Saturdays, Sundays, Mondays, and Tuesdays), and number of guests. The interface is available in English. When you reach the notes or request field, copy and paste the following phrase exactly as written:<\/p>\n<p><strong>\u9cf3\u6765\u725b\u5e0c\u671b<\/strong><\/p>\n<p>This tells us you're requesting the Horai Wagyu bowl. You don't need to know what it means or how to pronounce it \u2014 just paste it in. Our team will confirm your reservation and prepare accordingly.<\/p>\n<p>One more thing worth knowing: our business calendar changes monthly. Even during WCS season, we follow our scheduled days (Saturday, Sunday, Monday, Tuesday), but occasional irregular closures do apply. Before your visit, it's worth checking our monthly business calendar on Instagram to confirm we're open on your chosen day. The calendar is posted at the start of each month.<\/p>\n<h2>What If You Can't Reserve? Your Walk-In Strategy<\/h2>\n<p>Not everyone plans three weeks ahead. Some of the best meals happen on a spontaneous afternoon in Osu. If you're walking in without a reservation, there are two things that maximize your chances.<\/p>\n<p>First: arrive at 11:00, right at opening. Horai Wagyu is allocated on a first-come basis once the doors open. Early arrival on a non-peak day often means you'll be fine without a reservation.<\/p>\n<p>Second: know that Mikawa Beef Rare Gyudon is always available. Mikawa Beef is sourced from Aichi's Mikawa region, raised on okara feed with lactic acid bacteria gut management, and prepared using the same proprietary two-stage cooking technique that delivers our signature rare texture safely. It's a different beef with its own character \u2014 not a fallback, but a genuine second signature dish. Starting from \u00a51,800 for the Fumoto (100g beef, 200g rice), it's the most accessible way to experience what makes Itadaki's cooking approach distinct.<\/p>\n<p>If you'd like to understand more about how we achieve that rare texture safely \u2014 something that comes up often with first-time guests \u2014 we've written in detail about <a href=\"https:\/\/itadaki8.com\/en\/?p=533\">the two-stage cooking technique behind our rare wagyu preparation<\/a>.<\/p>\n<blockquote>\n<p>\"I discovered Itadaki through Google Maps and it became the best meal of our Japan trip.\"<\/p>\n<p>  <cite>\u2014 Guest review<\/cite>\n<\/p><\/blockquote>\n<p>That's how a lot of our international guests find us \u2014 a search, a map pin, an instinct to try something unfamiliar. But the guests who arrive with a reservation for Horai Wagyu tend to describe something a little different from those who stumble in: they describe a meal they were genuinely anticipating, and that anticipation becomes part of the experience itself.<\/p>\n<h2>Planning Your Osu Day Around Itadaki<\/h2>\n<p>We're a lunch-only restaurant, open from 11:00 to 15:00 (last order 30 minutes before closing). That timing works well with an Osu WCS day \u2014 visit Osu Kannon Temple in the morning, explore the shopping street, stop in for lunch at Itadaki, then continue into the afternoon events. Or reverse it: arrive at Yabacho Station, eat first, then spend the rest of the day in costume without the distraction of wondering where to eat.<\/p>\n<p>Hisaya-odori Garden Flarie, a free-admission urban garden featured in major English travel guides, is just a three-minute walk from Yabacho Station \u2014 the same station as Itadaki. If you're looking for a quiet, photogenic spot before or after your meal, it's worth the detour.<\/p>\n<p>For anyone navigating Osu for the first time with accessibility in mind, we've also covered some useful context in our piece on <a href=\"https:\/\/itadaki8.com\/en\/?p=335\">barrier-free options in Nagoya's Osu area<\/a> \u2014 relevant for any visitor thinking through logistics in the district.<\/p>\n<p>Itadaki is on the second floor and requires a staircase. Staff may be able to assist with luggage or bags depending on how busy the restaurant is at the time, though we can't guarantee that in advance. The sofa seating inside makes it one of the more comfortable spots in the area once you're up and settled.<\/p>\n<p>Whether you're here for WCS, for Osu, or simply because a map pin caught your eye \u2014 there's a bowl here with your name on it. The Horai Wagyu one just needs to be reserved first.<\/p>\n<p>For our complete menu, access details, and store information, visit our official page at <a href=\"https:\/\/itadaki8.com\/english\/\">https:\/\/itadaki8.com\/english\/<\/a><\/p>\n<div class=\"sag-cta sag-cta--close\">\n<p class=\"sag-cta__bridge\">With one or two days in Nagoya, there's no margin for arriving to a sold-out sign. Securing your Horai Wagyu reservation now \u2014 with \u9cf3\u6765\u725b\u5e0c\u671b in the notes field \u2014 is the one action that turns this from a 'maybe' into the meal you'll be telling people about when you get home.<\/p>\n<p class=\"sag-cta__action\"><a href=\"https:\/\/yoyaku.tabelog.com\/yoyaku\/net_booking_form\/index?rcd=23081531\" target=\"_blank\" rel=\"noopener noreferrer\">Secure Your Rare Wagyu Experience Before WCS Weekend<\/a><\/p>\n<\/div>\n<\/article>\n<p><script type=\"application\/ld+json\">{\"@context\":\"https:\/\/schema.org\",\"@type\":\"LocalBusiness\",\"name\":\"Itadaki - The Original Rare Wagyu Gyudon\",\"url\":\"https:\/\/itadaki8.com\/en\",\"address\":\"4-1-20 Osu 2F, Naka-ku, Nagoya-shi, Aichi 460-0011, Japan\",\"areaServed\":\"Itadaki serves foreign visitors from around the world who are traveling in the Nagoya area.
