10 Facts About Samurai Nagoya That Every History Fan Should Know
gotowpEvery time cherry blossom season rolls around, I find myself doing what I love most on a day off — wandering through Nagoya's older neighborhoods, poking into temple grounds, and thinking about just how much history is packed into this city. Most visitors rush through Nagoya on the Shinkansen between Tokyo and Kyoto without ever stepping off the platform. That, honestly, is one of the great missed opportunities in Japanese travel.
I'm Masayuki Goto, founder of Itadaki in Osu — the restaurant that invented Rare Wagyu Gyudon. But before I spend my days sourcing ultra-rare Horai Wagyu from Okumikawa and perfecting our two-stage cooking technique, I'm a Nagoya local who genuinely loves this city. And nowhere does Nagoya's character reveal itself more clearly than in its samurai history.
So here are 10 facts about Samurai Nagoya that I think every history fan should carry with them — especially if you're planning a visit.
Who This Is For
- ✅ History enthusiasts planning a visit to Nagoya Castle, Atsuta Shrine, or Inuyama Castle
- ✅ Travelers on the Golden Route (Tokyo–Kyoto–Osaka) curious about what Nagoya actually offers
- ✅ Samurai and Sengoku-era fans who want insider knowledge beyond the guidebooks
- ✅ Visitors wondering what to do for a full day in Nagoya — and where to have a memorable lunch
- ✅ Anyone asking: "Is rare wagyu safe to eat?" — and looking for honest answers alongside sightseeing tips
1. Nagoya Is the Birthplace of All Three Unifiers of Japan
This is the one fact that stops most foreign visitors cold. Oda Nobunaga, Toyotomi Hideyoshi, and Tokugawa Ieyasu — the three warlords who ended a century of civil war and unified Japan — were all born in what is now Aichi Prefecture. No other region on earth produced this concentration of historical influence in a single generation. When locals say Nagoya is a "samurai city," this is what they mean.
2. Nagoya Castle Was Built as a Statement of Power
Tokugawa Ieyasu ordered the construction of Nagoya Castle in 1610 — not merely as a fortress, but as a deliberate demonstration that the Tokugawa clan controlled the center of Japan. The castle's iconic golden shachihoko (mythical tiger-headed fish) atop each corner tower became symbols of the family's authority. The castle grounds are among the most complete in Japan and well worth a half-day of your time.
3. Atsuta Shrine Houses One of Japan's Three Imperial Treasures
The Kusanagi-no-Tsurugi — the Grass-Cutting Sword — is one of the three sacred objects that symbolize the Japanese imperial lineage, and it is enshrined at Atsuta Shrine in Nagoya. Before the Battle of Okehazama in 1560, Oda Nobunaga himself prayed at Atsuta for victory. He won, against overwhelming odds, and the rest is history. Visiting Atsuta feels less like a tourist stop and more like standing inside the origin story of modern Japan.
4. The Battle of Okehazama Happened Just South of the City
In 1560, Nobunaga's force of approximately 2,000 soldiers defeated an army of 25,000 led by Imagawa Yoshimoto — a battle so improbable it reads like fiction. The site is just a short drive from central Nagoya. For Sengoku enthusiasts, standing at the monument there and imagining the sudden summer storm that helped Nobunaga's ambush is a genuinely moving experience.
5. Toyotomi Hideyoshi Was Born a Peasant in Nakamura
Nakamura-ku, now a residential district of Nagoya, was the birthplace of Hideyoshi — a man who rose from farming stock to become regent of all Japan. Nakamura Park, built on the site of his birthplace, contains a shrine and a large statue. It's rarely crowded with foreign visitors, which makes it feel like a genuine local discovery. I've walked through there on quiet winter mornings and found it genuinely stirring.
6. Inuyama Castle Is One of Japan's Only Remaining Original Castles
Just 30 minutes north of Nagoya by train, Inuyama Castle dates to 1537 and is one of only twelve castles in Japan designated as National Treasures. Unlike reconstructed castles, Inuyama's keep is original — you climb steep wooden stairs worn smooth by centuries of footsteps. The view from the top, over the Kiso River, is extraordinary. If you're spending more than a day in Nagoya, Inuyama is essential.
7. Shikemichi Preserves the Merchant World That Supported the Samurai
One of my personal favorite corners of Nagoya is Shikemichi (四間道) — a preserved Edo-period merchant district near Nagoya Station with 300-year-old warehouses and cobblestone-lined streets. The unique Yanegami-sama rooftop shrines found here exist nowhere else in Japan. It's a quiet, atmospheric contrast to the energy of Osu and Sakae. Hidden cafés and restaurants occupy restored traditional buildings, and on a weekday morning you can walk through it almost entirely alone. Samurai cities needed merchant quarters, and this is one of the most intact examples that survives.
✓ Key Takeaways
- Nagoya produced all three of Japan's great unifiers — Nobunaga, Hideyoshi, and Ieyasu — making it unparalleled in samurai history
- The city's historical sites range from major landmarks (Nagoya Castle, Atsuta Shrine) to hidden local gems (Shikemichi, Nakamura Park) worth exploring off the beaten path
- A half-day of samurai sightseeing pairs naturally with a lunch stop in Osu — both are walkable from Yabacho Station
8. The Owari Tokugawa Clan Left a Museum Worth Visiting
The Tokugawa Art Museum in Nagoya holds one of Japan's most significant collections of samurai-era artifacts — including the original illustrated scrolls of The Tale of Genji, designated as National Treasures. What strikes me every time I visit is how personal the objects feel: lacquered sword cases, armor worn in actual battles, tea ceremony sets used by people whose decisions shaped Japan's history. It's not a large museum by international standards, but the depth of the collection is remarkable.
9. Nagoya's Food Culture Is Inseparable from Its Samurai Heritage
Hatcho miso — the deeply fermented, almost black soybean miso produced in Okazaki City — has been made continuously for over 600 years, originally supplying Tokugawa armies with high-protein provisions for long campaigns. At Itadaki, we use Hatcho miso from Okazaki in our miso soup, as part of our commitment to keeping every ingredient within Aichi Prefecture. It's a small but genuine link to the same culinary tradition that nourished the samurai who built this region.
10. Nagoya's Samurai Story Is Still Being Written
What I find fascinating as someone who's spent years thinking about Nagoya's identity is how alive this history feels in daily life here. The 2026 Asian Games are coming to Nagoya — a city that was once the administrative heart of feudal Japan, now hosting one of Asia's largest sporting events. New architecture like IG Arena, designed by Kengo Kuma and opened in July 2025, sits in a city still defined by a castle that Tokugawa built to last forever. The contrast is what makes Nagoya genuinely interesting, not just historically, but as a place to be right now.
A Note on Rare Wagyu — Because History Works Up an Appetite
After a morning walking Nagoya Castle grounds or exploring Shikemichi's cobblestoned lanes, you'll want somewhere to sit down and eat something worth remembering. Itadaki is a 4-minute walk from Yabacho Station Exit 4, right in the heart of Osu — which puts it within easy reach of every site I've described in central Nagoya.
One question I hear often from Western visitors: Is rare wagyu actually safe to eat? It's a completely fair question. In the US and Europe, health guidelines generally advise against undercooked beef, and the idea of "rare-style" preparation can sound alarming to anyone raised with those standards.
Here's the honest answer. Our Rare Wagyu Gyudon is prepared using a proprietary two-stage cooking technique that heats the beef to over 70°C at the core — fully meeting Japan's Ministry of Health, Labour and Welfare food safety standards. The result feels like eating rare beef, but is scientifically and legally compliant with Japan's strict regulations. We developed this technique specifically so that guests from any country could enjoy the experience with complete peace of mind. We also hold a Certified Food Sanitation Supervisor license and operate under Aichi Prefecture Public Health Center authorization.
The beef itself — Horai Wagyu from Okumikawa, produced by only 3 farms in Japan with just 300 heads raised annually — is sourced under direct partnership with those farms. Rigorous quality control at the farm level is part of what makes this ingredient extraordinary.
"The lunch was the highlight of my Nagoya trip — I'm telling all my friends about it."
— Guest review
That kind of response means everything to us. And it's exactly what I had in mind when I designed this restaurant: a place where the history of Aichi's ingredients, the craft of the preparation, and the warmth of genuine hospitality come together in a single bowl.
Horai Wagyu is strictly limited to 10 bowls per day. If you're planning a history-focused day in Nagoya and want to make sure the bowl is waiting for you, I'd encourage you to reserve in advance. When making your reservation on Tabelog, copy and paste the following into the notes field to request Horai Wagyu: 鳳来牛希望
