Nagoya Castle vs Inuyama Castle: Which Trip Pairs With Itadaki Lunch

A message came in through Instagram a few weeks ago that I still think about. A traveler from Hong Kong — on their third trip to Japan — wrote something like: "I've done Osaka, Kyoto, Tokyo many times. I want to see the castles near Nagoya but I also want to eat somewhere that locals actually eat, not just another tourist spot. Can you help me plan the day?"

That question is one I hear often, and it gets to the heart of what a certain kind of traveler is really after. Not just another Instagram photo in front of a famous gate. A day that belongs to them — one they'll still be talking about a year later.

So let me walk through the two most likely castle options — Nagoya Castle and Inuyama Castle — and share honestly which kind of traveler each trip suits, and how a lunch stop in Osu fits into each plan.

Who This Is For

• ✅ Repeat visitors to Japan who want to go beyond the well-known Golden Route
• ✅ Travelers weighing Nagoya Castle vs Inuyama Castle and wanting a practical, honest comparison
• ✅ Anyone planning a full day out who wants a genuinely local lunch — not a tourist-area set menu
• ✅ History enthusiasts curious about Aichi's samurai legacy and how to pair it with authentic regional food
• ✅ Travelers who discovered Nagoya on their own and want to plan a day that feels truly "theirs"

Nagoya Castle: Depth Over Distance

Nagoya Castle is the symbolic heart of the city — and for good reason. As the former seat of the Owari Tokugawa clan and one of Japan's greatest reconstructed castles, it carries centuries of weight. The castle grounds themselves are expansive, with the Honmaru Goten (the restored palace interior) being one of the few places in Japan where you can walk through a recreated Edo-period lord's residence up close.

For a repeat visitor who skipped Nagoya on earlier trips, this is still a genuinely rewarding morning. It's not a "tourist trap" — locals visit on weekends. And unlike many Japanese castles, Nagoya's grounds are large enough that you can spend two to three hours without feeling rushed.

What makes Nagoya Castle work particularly well as a pairing with lunch in Osu is the geography. The castle sits in the north of the city center, and Osu — where Itadaki is located — is a roughly 15-minute subway ride south. The route is simple: exit the castle, walk to Shiyakusho Station, take the Meijo Line, and get off at Yabacho. Four minutes on foot and you're there.

This means a morning at Nagoya Castle flows naturally into a midday arrival in Osu — at exactly the right time for lunch service, which runs from 11:00 to 15:00 (Tuesday, Monday, Saturday, and Sunday; always check the monthly calendar on Instagram for irregular closures). You're not scrambling. You're not rushing. You walk out of the castle grounds, step onto the subway, and arrive at Osu feeling like someone who actually knows how this city works.

Inuyama Castle: The Reward for Going Further

Inuyama Castle is a different proposition entirely. It's one of only five castles in Japan designated as a National Treasure, and it's the oldest surviving castle keep in the country. Standing on a bluff above the Kiso River, it offers a view that genuinely earns the walk up. No reconstructed walls — the original wood, the original stone. If Nagoya Castle is impressive in scale, Inuyama Castle is intimate in authenticity.

Getting there from central Nagoya takes about 30 minutes on the Meitetsu Inuyama Line from Meitetsu Nagoya Station — affordable and easy to navigate. The castle town below (Honmachi street) has a preserved Edo-period streetscape that still functions as a real shopping street, not a theme park recreation. Vendors selling local sweets, small sake shops, craft stores — the kind of place repeat visitors tend to fall for immediately.

The honest drawback: the round trip adds time to your day. If you want to be in Osu for lunch, you're looking at a morning departure, a focused castle visit (one to two hours is usually enough), and then retracing your route back toward Nagoya city — getting off at or near Sakae or Yabacho to reach Itadaki. It's achievable, but it requires intentional pacing. Late risers or anyone who plans to linger in the castle town may find themselves arriving at Osu uncomfortably close to last order (30 minutes before 15:00).

That said, for the traveler who moved to Japan in their own timeline — who has already seen the famous places and wants the less-photographed corners — Inuyama is exactly the kind of discovery that stays with you. The comparison between what you can find on the Inuyama route versus what Osu offers is something I've written about more directly in this piece comparing Inuyama and Nagoya Osu for deeper discovery.

✓ Key Takeaways

• Nagoya Castle pairs effortlessly with an Osu lunch — 15 minutes by subway, relaxed pacing, no compromise on either experience.
• Inuyama Castle suits the traveler who values authentic antiquity and is willing to manage timing carefully to reach Osu for lunch.
• Both routes end in the same place: Osu — a neighborhood that most English-language guidebooks still undercover, and where a genuine local food discovery is waiting.

Where Both Routes Converge: Osu and the Lunch That Completes the Day

Here's what both itineraries share: they bring you to Osu. And Osu, for the kind of traveler this article is written for, is itself part of the discovery.

Osu is not the Nagoya that most international visitors see. It doesn't appear prominently in the standard guidebook circuit. It's the neighborhood where Nagoya locals shop on weekends — a 1,200-shop street with over 400 years of history, anchored by Osu Kannon Temple, layered with vintage electronics shops, cosplay culture, and hidden food specialists. The sort of place a Japanese food writer would describe with quiet pride: "This is where I actually eat."

Itadaki sits on the second floor of a building in the heart of this district. We specialize in one thing: Rare Wagyu Gyudon — a culinary concept that didn't exist before we opened in April 2022. The idea was simple in principle and took years to develop in practice: take Japan's most humble comfort food, the beef bowl, and reimagine it using Aichi Prefecture's rarest and finest ingredients, cooked with a proprietary two-stage technique that delivers a rare mouthfeel while fully meeting Japan's food safety standards.

Every ingredient — the beef, the rice, the sauce, the pickles, the egg — comes from Aichi Prefecture. The Horai Wagyu used in our signature bowl is raised by just three farms in Japan, with only 300 heads produced annually. That's not a marketing line. It's a fact that shapes how we source, how we cook, and how much we can serve each day (strictly 10 bowls of Horai Wagyu).

"I discovered Itadaki through Google Maps and it became the best meal of our Japan trip."

— Guest review

That kind of review means something different to me than a five-star rating. It tells me the discovery itself was part of the experience — that finding us felt like something they did, not something a tour operator arranged for them. That's exactly the kind of lunch we set out to create.

Which Castle Trip Should You Choose?

Let me be direct about this, because "it depends" is only useful if I explain on what.

Choose Nagoya Castle if: You want a full, unhurried day that combines historical depth with genuine neighborhood exploration. The castle grounds alone justify a two-hour visit, and the Meijo Line delivers you to Osu with time to stroll through the shopping street or visit Osu Kannon before lunch. This is the more forgiving itinerary, and it works equally well for solo travelers, couples, and families.

Choose Inuyama Castle if: You've already seen Nagoya Castle, or you specifically want the experience of Japan's oldest surviving castle keep in a preserved castle town. Plan to leave central Nagoya by 9:00 or 9:30, spend no more than two hours in Inuyama, and aim to arrive in Osu by 12:30 at the latest. If Horai Wagyu is important to you — and given that it's limited to 10 bowls a day — I'd recommend securing a reservation via Tabelog before you travel, regardless of which castle you visit.

A Note on What "Hidden Gem" Actually Means

I want to say one more thing, because it's something I genuinely believe.

The travelers who write to us — the ones who've been to Japan six, eight, ten times — aren't looking for "hidden" in the sense of obscure or inconvenient. They're looking for places where the story behind the food is real. Where the chef or the founder made a genuine choice — not to follow a trend, but to solve a problem, honor a farmer, or create something that simply didn't exist before.

That's what Itadaki is. We opened because small Aichi farmers were struggling during the pandemic and needed a partner who would source from them directly and build a business around their ingredients. The name "Itadaki" comes from "itadakimasu" — the expression of gratitude spoken before every meal in Japan. It's not a brand name. It's a philosophy.

Whichever castle you visit this August — and August in Nagoya is alive, warm, and full of energy — the lunch that follows can be more than a meal. It can be the part of the day you tell the story about.
