7 Historic Aichi Castle Towns and Their Nagoya Lunch Pairings

You've spent the morning walking through the grounds of a 400-year-old castle, and now you're hungry — genuinely, deeply hungry — standing on a street in Nagoya where every restaurant sign is in Japanese. You pull out your phone, open Google Maps, and start scrolling. One place catches your eye. The photos look extraordinary: thin slices of pale, glistening wagyu draped over a bowl of rice, a golden egg yolk sitting on top like a crown. But then the anxiety creeps in. Can I actually order this? Will anyone speak English? What if I do something wrong?

That moment of hesitation is something we hear about often at Itadaki. And it's exactly why this article exists.

Aichi Prefecture is home to some of Japan's most fascinating castle towns — from the internationally famous to the quietly magnificent. Each one deserves a full morning of exploration. And each one pairs naturally with a lunch in Osu, Nagoya, at Japan's original Rare Wagyu Gyudon specialty restaurant. But before we map out those pairings, let's address the question that matters most to international visitors: Can you enjoy Itadaki without speaking a word of Japanese? The short answer is yes — and here's exactly how.

Who This Is For

• ✅ International travelers visiting Aichi's castle towns and looking for a memorable lunch in Nagoya
• ✅ Anyone anxious about ordering at an authentic Japanese restaurant without Japanese language skills
• ✅ Wagyu enthusiasts who want to explore beyond Kobe and Matsusaka beef
• ✅ Repeat Japan visitors ready to discover what Aichi Prefecture has been quietly perfecting for centuries
• ✅ Travelers planning Nagoya as part of a broader Central Japan itinerary including Shirakawa-go or Takayama

The Language Barrier That Keeps Travelers Away From the Best Meals

Here's something worth saying plainly: the most memorable food experiences in Japan are almost never at the restaurants with English signage out front. They're at the specialty shops tucked into second-floor spaces in historic shopping districts, run by people who care deeply about a single thing and have spent years perfecting it. The language barrier, real as it is, has a habit of steering travelers toward the familiar — and away from the extraordinary.

At Itadaki, founder Masayuki Goto built the restaurant with international visitors genuinely in mind — not as an afterthought, but as part of the original concept. When he opened in Osu in April 2022, Goto's vision was to introduce Aichi Prefecture's premium ingredients to the world. That mission only makes sense if visitors from around the world can actually experience the food without frustration.

The solution at Itadaki is practical and immediate: a fully printed multilingual menu available in English, Simplified Chinese, and Korean. Not a QR code that links to a blurry PDF. A physical menu, with photographs of every dish, clearly listed prices, and ingredient explanations written in plain language. You can point to what you want. You can read what's in it. You can see what it looks like before it arrives.

For a dish like Rare Wagyu Gyudon — which is genuinely unlike anything most visitors have encountered before — this matters enormously.

The Five-Step Visual Guide: Because Rare Gyudon Has Its Own Ritual

One of the most common questions we receive from first-time visitors isn't about the beef itself. It's about the egg. A whole raw Nagoya Cochin egg arrives alongside your bowl. What do you do with it? Do you break it directly onto the beef? Do you mix everything together at once? Is there a right way?

There is — and the printed menu walks you through it, step by step, with photographs.

The experience unfolds in five deliberate stages:

1. Separate the egg. Pour the egg white into your miso soup, and place the golden yolk directly on top of the wagyu.
2. Taste the wagyu first. Before mixing anything, take a piece of the rare-style beef on its own. Let the flavor of Horai Wagyu — raised in Okumikawa, Aichi, on the sake lees of Horaisen Sora — speak for itself.
3. Mix in the yolk. Combine the golden yolk with the beef for a richer, silkier mouthfeel that transforms the whole bowl.
4. Add the condiments. The tabletop holds pickled ginger from Kimura Farm in Inazawa, chopped seaweed from Himakajima in Mikawa Bay, chirimen jako (dried whitebait from Minamichita), and Itadaki's original 8-spice blend. Add them gradually to discover new layers of flavor.
5. Finish with wasabi. A small amount of Itadaki's original wasabi at the end cleanses the palate with a bright, refreshing note.

Every step is illustrated in the menu you hold in your hands. No Japanese required. No guessing. The ritual becomes part of the experience — and one of the reasons guests describe the meal as a culinary journey rather than just a lunch.

✓ Key Takeaways

• Itadaki's printed multilingual menu (English, Chinese, Korean) with photos removes the ordering anxiety entirely — no Japanese needed to enjoy the meal.
• The five-step visual eating guide in the menu transforms Rare Wagyu Gyudon from an unfamiliar dish into a structured, enjoyable ritual any visitor can follow.
• Translation apps work perfectly well in the restaurant if you have additional questions for staff.

7 Aichi Castle Towns — and Where to Have Lunch After

Now for the pairings. Aichi Prefecture is remarkable for the sheer density of its castle history. These seven towns each tell a different story — and each one brings you close enough to Osu to make Itadaki a natural lunch destination.

1. Nagoya — The city that gave Japan three of its greatest warlords: Oda Nobunaga, Toyotomi Hideyoshi, and Tokugawa Ieyasu. Nagoya Castle, with its famous golden shachi (tiger-fish) roof ornaments, is one of Japan's most iconic landmarks. From the castle, Itadaki in Osu is easily reachable by subway — and the Osu district itself, with its 400-year-old shopping street and the ancient Osu Kannon Temple, extends the historical mood beautifully. For a full itinerary that connects the castle district with Osu, this step-by-step guide to a Nagoya Castle morning and Osu Kannon afternoon maps out the route in detail.

2. Inuyama — Home to Japan's oldest original castle, a National Treasure perched on a bluff above the Kiso River. The town below is beautifully preserved, with traditional townhouses and sake breweries along the river road. Inuyama is about 40 minutes by Meitetsu Line from central Nagoya, making it a perfect morning excursion before an Itadaki lunch. For more on finding lunch between Nagoya and Inuyama Castle, we've covered the logistics in a dedicated guide.

3. Okazaki — The birthplace of Tokugawa Ieyasu and home to Okazaki Castle, situated beside the Oto River. Okazaki is also the home of Hatcho miso — the dark, intensely flavored miso paste that forms the base of Itadaki's miso soup. There's a pleasing circularity in visiting Okazaki in the morning and tasting its most famous ingredient in a bowl at Itadaki for lunch.

4. Kiyosu — Oda Nobunaga's first great castle, now reconstructed on its original site. Kiyosu was the staging ground for some of Japan's most dramatic 16th-century battles. The castle is compact and easy to visit within half a morning, leaving ample time for the short transit to Nagoya and lunch in Osu.

5. Komaki — Komaki Castle sits on a low hill in northern Nagoya's outskirts and was used by Toyotomi Hideyoshi during the Battle of Komaki and Nagakute in 1584. Less visited than Nagoya or Inuyama, it offers a quieter, more reflective castle experience — and an easy return route through Nagoya.

6. Tsushima — Not a castle town in the traditional sense, but Tsushima Shrine and the surrounding merchant district hold centuries of history tied to water transport and the powerful daimyo of the Sengoku era. The seasonal atmosphere along the waterways is striking. Tsushima is accessible via Meitetsu and pairs well with a midday return to central Nagoya.

7. Atsuta — Atsuta Shrine, one of Shinto's most sacred sites, has guarded one of Japan's Three Imperial Treasures for nearly two millennia. The forested shrine grounds in the middle of modern Nagoya create an atmosphere unlike anywhere else in the city. From Atsuta, Osu is a short subway ride — and Atsumi Peninsula's pickled radish (Atsumi Ichō-zuke), served alongside every Itadaki bowl, connects even this coastal landmark to what arrives on your table.

"Perfect lunch during our Nagoya stay before our Shirakawa-go trip the following day."

— Guest review

That review says something important. Many visitors to Aichi's castle towns are also making day trips into the Gifu highlands — Shirakawa-go, Takayama, Gujo Hachiman. Nagoya becomes the natural base: historically rich in the morning, satisfyingly nourishing at lunch, and a launchpad for the mountains the next day. The 10 bowls of Horai Wagyu available each day at Itadaki tend to go during peak hours, so reserving through Tabelog in advance is genuinely worth doing before you start planning the rest of your itinerary.

A Practical Note: What to Do If You Have Questions at the Table

Even with the multilingual menu in hand, there are moments when you might want to ask something more specific — whether a condiment contains a particular allergen, whether the egg can be removed from your bowl, or how to pronounce the name of the dish you're about to photograph. A few things to know:

• Point-and-order works perfectly. The menu is designed so that you can order your entire meal by pointing. Prices, photos, and portion sizes are all clearly shown.
• Translation apps are welcome. There's no awkwardness in using Google Translate or a similar app at the table. Staff are accustomed to it and will respond naturally.
• Allergen information is in the menu. Soy and wheat are present in the soy sauce and miso. Egg comes with every bowl but can be removed for a ¥150 reduction. Sesame is contained in the complimentary chirimen topping on the tabletop — simply leave it if you need to avoid it. Itadaki does not hold Halal certification.
• Reservations can be made in English through Tabelog's online booking system. Noting any dietary needs in the booking comments is a good way to prepare the kitchen in advance.

The Ingredient That Connects Aichi's Castle Towns to Every Bowl

There's a reason Itadaki sources every single ingredient from Aichi Prefecture — not as a marketing point, but as a philosophical commitment. The Hatcho miso in your soup comes from Okazaki, the same city where Tokugawa Ieyasu was born. The pickled radish came from Atsumi Peninsula, facing the same bay that feudal merchants once crossed by boat. The white soy sauce base of the "magic sauce" is pressed in Hekinan. The shiso leaves grow in Toyohashi. The wagyu was raised in the mountains of Okumikawa.

When you visit Nagoya's castle towns and then sit down to a bowl at Itadaki, you're not just eating a meal between sightseeing stops. You're tasting a landscape — the same landscape the warlords, merchants, and farmers of Aichi have shaped for centuries. That continuity, quiet as it is, is what makes the experience worth seeking out.
