7 Facts About Osu Dining That Every Conference Visitor Should Know

Here's a number that surprises most conference visitors arriving in Nagoya for the first time: only 10 bowls of Horai Wagyu are served at Itadaki each day — full stop. Not 10 per seating, not 10 per shift. Ten bowls, total, for the entire day. Given that Horai Wagyu is raised by just 3 farms in Japan, with only 300 heads produced annually out of a national wagyu population of roughly 500,000, this isn't a marketing limit — it's a simple reality of supply. For conference visitors squeezing a Nagoya lunch between a morning session and an afternoon panel, arriving to find it sold out isn't just disappointing. It's a missed opportunity that's very difficult to recover from on a tight itinerary.

This article walks you through 7 practical facts about dining in Osu — specifically the reservation question, the timing question, and the "what if I miss it" question — so you can plan your conference lunch with confidence rather than guesswork.

Who This Is For

• ✅ Conference and MICE visitors with limited time in Nagoya who want to make their one lunch count
• ✅ Travelers who have heard about Horai Wagyu and want to know how to actually secure a bowl
• ✅ Anyone unfamiliar with Japanese reservation platforms like Tabelog and wondering how to navigate them in English
• ✅ Walk-in visitors who can't plan ahead but still want to maximize their chances
• ✅ First-time visitors to Osu who want to understand the neighborhood before they arrive

Fact 1: Horai Wagyu Is Capped at 10 Bowls a Day — and It's Not a Gimmick

When Masayuki Goto founded Itadaki in April 2022, the limit on Horai Wagyu wasn't designed to create buzz. It exists because the beef itself is genuinely scarce. Raised in Okumikawa in Aichi Prefecture and fed on sake lees from the premium local sake Horaisen Sora, Horai Wagyu produces a flavor profile unlike anything most wagyu enthusiasts have encountered — a balance of delicate marbling and lean meat depth that other wagyu don't replicate. That rarity means supply is tight, and Itadaki refuses to compromise quality by sourcing beyond what the farms can provide.

For a conference visitor with a 90-minute lunch window, this cap matters enormously. Peak dining hours in Osu typically fall between 12:00 and 13:30. If you arrive at 12:30 without a reservation, the Horai Wagyu is very likely already gone.

Fact 2: Tabelog Online Reservations Work in English — Here's Exactly How

Many foreign visitors assume that Japanese reservation platforms require Japanese language skills. Tabelog's reservation interface is available in English, and the process is more straightforward than most people expect. Follow these steps:

1. Search for Itadaki on the Tabelog website or use the direct reservation link.
2. Select your date and party size. Remember that Itadaki operates on a limited schedule — lunch service only, open Saturday, Sunday, Monday, and Tuesday (plus public holidays from 09:00). Wednesday through Friday are closed. Always confirm the date against the current monthly calendar before booking.
3. In the notes or requests field, copy and paste the following Japanese phrase: 鳳来牛希望 (pronunciation: Hōraigyu kibō, meaning "I would like Horai Wagyu"). This signals to the kitchen to set aside a Horai Wagyu bowl for your reservation.
4. Complete your booking. You'll receive confirmation by email.

That four-step process is all it takes. No phone calls, no Japanese fluency required. The phrase 鳳来牛希望 does the work for you — just copy it and paste it directly.

One important note: last order is 30 minutes before closing (closing time is 15:00, so last order is 14:30). If your conference schedule runs long and you arrive close to that window, plan accordingly.

Fact 3: Walk-In Visitors Have a Real Strategy Too

Not every conference itinerary allows for advance planning. If you're a walk-in visitor, you're not out of options — but timing is everything.

Arriving at 11:00 opening is by far the most reliable walk-in strategy. Itadaki opens at 11:00, and arriving at or just before opening gives you the highest chance of securing one of the 10 daily Horai Wagyu bowls without a reservation. Conference sessions in Nagoya typically begin at 09:00 or 09:30, making an 11:00 lunch entirely realistic if your morning programme wraps on time.

If the Horai Wagyu has already sold out when you arrive, Mikawa Beef Rare Gyudon is always available. Mikawa Beef comes from Aichi's Mikawa region, raised on okara feed with lactic acid bacteria gut management — a completely different beef with its own distinctive character. It's prepared using the same proprietary two-stage cooking technique as the Horai Wagyu, delivering the same signature rare-style texture while fully meeting Japan's food safety standards. Many guests who came specifically for Horai Wagyu and ended up with Mikawa Beef have left just as satisfied.

✓ Key Takeaways

• Horai Wagyu is capped at 10 bowls daily — reserving via Tabelog and adding 鳳来牛希望 to the notes field is the only guaranteed way to secure it.
• Walk-in guests who arrive at 11:00 opening have the best chance without a reservation.
• Mikawa Beef Rare Gyudon is always available as a second signature option, prepared with the same technique.

Fact 4: The English Menu Removes the Guesswork

One anxiety that conference visitors often carry into unfamiliar restaurants is not knowing how to order — or how to eat the dish correctly. Itadaki addresses this directly. Printed menus are available in English, Simplified Chinese, and Korean, and a photographic five-step guide explaining exactly how to enjoy the gyudon is included with every bowl.

"The English menu with clear serving instructions made the experience stress-free."

— A guest at Itadaki

That five-step guide isn't decorative. It structures the eating experience deliberately: separating the Nagoya Cochin egg (white into the miso soup, yolk atop the beef), enjoying the wagyu in its purest form first, then mixing, then adding condiments, then finishing with wasabi. Each step changes the flavor profile of the bowl. For a conference visitor with 60 minutes at the table, having that structure removes uncertainty and lets you focus on the experience itself.

Fact 5: The Location Makes It Practical for Conference Schedules

Itadaki is located in Osu, on the 2nd floor of a building at 4-1-20 Osu, Naka-ku. From Yabacho Station Exit 4 (Meijo Subway Line), it's a 4-minute walk. From Nagoya Station, the journey takes approximately 10 minutes by subway: take the Higashiyama Line to Sakae, transfer to the Meijo Line, and alight at Yabacho.

For conference venues in Nagoya's central business district — including venues near Nagoya Station, Fushimi, and the broader Sakae area — this puts Itadaki well within a practical midday excursion. The lunch-only format (11:00–15:00) aligns naturally with a conference break, and the 18-seat interior — all sofa-style table seating — means the atmosphere is unhurried rather than rushed. Itadaki is not a conveyor-belt dining environment. There's space to eat deliberately and leave satisfied rather than hurried.

If you're planning your Nagoya itinerary around a conference and want to understand what else Osu has to offer in the same visit, the dining guide for corporate visitors to Nagoya covers several practical details worth knowing before you go.

Fact 6: Irregular Closures Are Real — Always Check the Monthly Calendar

This is the fact most likely to catch conference visitors off guard: Itadaki operates on a specific weekly schedule (Saturday, Sunday, Monday, Tuesday — plus public holidays), but irregular closures also apply. The monthly business calendar is published on Itadaki's official Instagram account.

For a conference visitor planning a single lunch in Nagoya, arriving on a day when Itadaki is unexpectedly closed is a frustrating outcome that takes 30 seconds to prevent. Before finalising your lunch plans, check the monthly schedule on Instagram to confirm the restaurant is open on your chosen date. This step takes less time than finding a parking spot in central Nagoya — and it's significantly more useful.

September 2026 falls during the Asian Games period, when visitor numbers across central Nagoya are elevated and dining spots in the Osu and Sakae area see higher demand than usual. If you're attending the Games or a conference coinciding with that period, the full Osu dining guide for Asian Games visitors has context that applies directly to your situation.

Fact 7: A Reservation Is Five Minutes of Work That Protects Your One Lunch in Nagoya

Conference visitors rarely have a backup lunch plan. When you're in Nagoya for one or two days, the margin for error is thin. The reservation process on Tabelog in English takes roughly five minutes. The phrase you need — 鳳来牛希望 — requires nothing more than copying and pasting. The payoff is a bowl of Horai Wagyu that 499,700 of Japan's wagyu cattle simply cannot match, prepared by a team trained to Goto's precise standards, served with ingredients sourced entirely from Aichi Prefecture, in a room where the atmosphere doesn't rush you out the door.

Goto built Itadaki on a direct-supply partnership with Horai Wagyu farms — a relationship that began from a genuine desire to support Aichi's small producers during a period when many struggled to find buyers. That philosophy — expressed in the restaurant's name, derived from itadakimasu, the Japanese expression of gratitude before eating — runs through every element of the experience. You're not just eating a beef bowl. You're eating the story of three farms, one region, and one founder who decided that gyudon deserved to be taken seriously.

Reserve early. Paste 鳳来牛希望 into the notes. Arrive at 11:00 if you can't. And if Horai Wagyu is gone, order the Mikawa Beef and discover that Aichi has more than one answer to the question of what wagyu can be.
