If You Cosplay at Osu Kannon, Add Itadaki to Your Summit Plans

Here's something that might surprise you: a significant number of visitors who plan to eat at Itadaki during World Cosplay Summit week end up walking right past our door. Not because they changed their minds — but because they simply couldn't find us. Osu's labyrinth of covered arcades, temple-side alleyways, and side streets has a way of swallowing even the most prepared traveler whole. Add a cosplay outfit, an armful of shopping bags from Osu's subculture stores, and the general sensory overload of Summit week, and it's genuinely easy to miss a 2nd-floor restaurant with a Japanese-language sign at street level.

So if you're planning to spend part of World Cosplay Summit day exploring around Osu Kannon — whether in full costume or casual clothes — this guide is specifically for you. We're going to walk through exactly how to get from Nagoya Station (or your hotel) to Itadaki's front door, what to look for when you get close, and why the rare wagyu gyudon waiting upstairs is worth every extra minute of navigation.

Who This Is For

  • ✅ Cosplay enthusiasts attending World Cosplay Summit and planning lunch in the Osu area

Why Osu Feels Like a Maze (And Why That's Part of Its Charm)

Osu has over 400 years of history as a merchant district, and its street layout reflects that. Unlike Nagoya's newer districts — which follow clean grid patterns — Osu grew organically around Osu Kannon Temple, with covered arcades branching off in multiple directions, underground passages connecting to the subway, and narrow side streets that don't always appear on digital maps.

During World Cosplay Summit, the district gets even more layered. Cosplayers gather near the temple forecourt, parade routes shift foot traffic through unusual angles, and temporary stalls fill some of the usual navigation landmarks. Google Maps in this area can place pins imprecisely — and because Itadaki is on the 2nd floor of a building on Osu's inner streets, there's no ground-level shopfront to catch your eye as you pass.

We hear this from visitors often. One guest told us: "I traveled to Nagoya specifically to eat here — it was 100% worth it." But that journey included a few minutes of searching before finally spotting the sign. So here's how to skip the search.

You now know the route from Yabacho Exit 4 — but Itadaki's hours during Cosplay Summit week are subject to the monthly schedule, and irregular closures do apply. Our Instagram shows the exact business calendar each month so you can confirm the date before you travel. Takes about 30 seconds to check.

The Clearest Route: From Nagoya Station to Itadaki's Door

The single most reliable way to reach Itadaki is via Yabacho Station, Exit 4 on the Meijo Subway Line. From there, it's a 4-minute walk. Here's the full journey from Nagoya Station:

  1. Take the Higashiyama Line from Nagoya Station toward Fujigaoka.
  2. Get off at Sakae Station — this is Nagoya's central hub and usually takes about 5–6 minutes.
  3. Transfer to the Meijo Line (circular line) at Sakae Station. The platforms are within the same station complex.
  4. Ride one stop to Yabacho Station — just 2 minutes on the train.
  5. Exit through Exit 4. Total time from Nagoya Station: approximately 10 minutes.

Once you're at Yabacho Exit 4, walk in the direction of Osu Kannon Temple. You're looking for a building with a sign that reads 「元祖レア牛丼 頂」 (pronounced Ganso Rea Gyudon Itadaki) at street level. When you see that sign, take the staircase up to the 2nd floor — that's Itadaki.

Itadaki is also within walking distance from Sakae Station, Kamimaezu Station, and Osu Kannon Station, so depending on where you're coming from during Summit week, any of these can work as your entry point. A direct Google Maps link is available on our official page at itadaki8.com/english/ — that pin is more precise than a general Osu address search.

✓ Key Takeaways

  • The easiest route is Yabacho Station Exit 4 (Meijo Line) → 4-minute walk → look for 「元祖レア牛丼 頂」 at street level → stairs to 2nd floor.
  • From Nagoya Station, the journey takes approximately 10 minutes total via Higashiyama Line to Sakae, then one stop on the Meijo Line.
  • Google Maps can be imprecise in Osu — use the direct pin link on our website for the most accurate navigation.

Knowing Horai Wagyu is capped at 10 bowls a day changes the calculus for Summit week — when the district is at its most crowded and lunch windows are tight. A Tabelog reservation locks in your bowl before you even board the subway at Nagoya Station. The reservation form is in Japanese, but the process is straightforward.

What's Behind the Sign: The Ingredients That Make the Journey Worth It

Once you climb those stairs, the reason this restaurant exists is sitting right there in front of you — and it starts long before the bowl reaches your table. Itadaki's founder Masayuki Goto built this restaurant on a single principle: every ingredient comes from Aichi Prefecture. Not most of them. Every single one.

The beef at the center of the bowl is where that commitment becomes extraordinary. The signature option — Horai Wagyu — comes from Okumikawa, a mountainous inland region of Aichi. Only three farms in Japan raise this breed, producing approximately 300 heads per year. To put that in context: Japan raises roughly 500,000 wagyu cattle annually. Horai Wagyu represents a fraction of a fraction of that total. The cattle are fed on sake lees from Horaisen Sora, a premium local sake, which contributes to a flavor profile that's distinctly different from better-known wagyu brands — lighter marbling, more defined lean-meat character, a cleanness on the palate that surprises most guests who arrive expecting richness alone.

The rice beneath the beef is Aichi no Kaori, an Aichi-grown premium variety, cooked in high-tech rice cookers that Goto adjusts annually to match each harvest's particular moisture and texture. The miso soup uses Hatcho miso and soybean miso from Okazaki City — one of Japan's most historically significant miso-producing towns. The pickles are traditional Atsumi Ichō-zuke from the Atsumi Peninsula. The shiso leaves are Aikei No.1 variety from Toyohashi. The egg — a Nagoya Cochin egg from Yamada Poultry Farm — is separated tableside: the white goes into the miso soup, the golden yolk rests atop the beef.

None of this is accidental sourcing. Goto developed direct partnerships with these farms in part because of the disruption many small Aichi producers experienced during the COVID-19 pandemic. Itadaki was conceived as a restaurant that could support those producers long-term — a farm-to-table model built on genuine relationships, not rotating supplier lists.

— Guest review

For guests who've spent the morning at the Osu Kannon parade viewing area or walking the cosplay photo spots around the shopping arcades, the bowl arriving at the table is a very different kind of experience from anything else on the Summit week itinerary. If you're interested in how this lunch fits alongside a full cosplay and sightseeing day, our guide on fitting Itadaki into your Cosplay Summit parade day schedule walks through the timing in more detail.

A Note on Timing, Cosplay, and Horai Wagyu Availability

A few practical details worth knowing before you plan your visit, especially during World Cosplay Summit week when foot traffic in Osu peaks significantly.

Cosplay is entirely welcome at Itadaki. Our guests arrive in everything from everyday clothes to elaborate fantasy costumes, and every visitor is treated with the same genuine warmth. The sofa seating — which fills most of the dining room — is considerably more comfortable than standard chairs for guests wearing layered or structured costumes. Counter seats are also available for solo visitors or pairs who prefer a quieter spot.

Horai Wagyu is limited to 10 bowls per day. During Summit week, demand rises, and those 10 bowls can sell out before the lunch rush ends. A reservation via Tabelog is strongly recommended if you want to be certain the Horai Wagyu option is waiting for you — rather than arriving to find only the Mikawa Beef bowls remaining (which are excellent in their own right, but a different experience). Itadaki is open Monday, Tuesday, Saturday, Sunday, and public holidays from 11:00 to 15:00, with last order 30 minutes before closing. September 7th, 2026 falls on a Monday, so we will be open. Check the monthly business calendar on our Instagram for any irregular closures around Summit week.

The building entrance is on street level, accessed by staircase. The restaurant is on the 2nd floor, and there is no elevator. Staff may be able to assist with items as conditions allow, though we cannot guarantee availability of assistance at any particular moment.

From the Sign on the Street to the Bowl on the Table

Osu is one of those districts that rewards people who look up, look twice, and follow a sign even when they're not entirely sure where it leads. The sign at street level — 「元祖レア牛丼 頂」 — is exactly that kind of invitation. The staircase takes less than ten seconds to climb. What's waiting at the top is a bowl built from three years of direct farm partnerships, a proprietary cooking method that delivers rare-style wagyu within Japan's food safety standards, and an unwavering commitment to sourcing every ingredient from Aichi Prefecture.

World Cosplay Summit week in Osu is one of the most energetic experiences Nagoya offers. Itadaki is a quiet counterpoint to it — a place to sit, eat slowly, and taste something genuinely rare before heading back out into the spectacle.

You've navigated the route, you know what's in the bowl, and you know the 10-bowl daily limit is real. The one remaining step is securing your seat before Summit week demand fills those slots. Tabelog online reservations are the only way to guarantee availability at Itadaki.
