When it comes to Nagoya castle towns, most tourists' first instinct is the high-rise commercial district around JR Nagoya Station, or Nagoya Castle, built by Tokugawa Ieyasu. But if you only know these two landmarks, you're missing out on the truly fascinating town stories of Owari Domain history.
The soul of a castle town lies not in the castle itself, but in the interaction between the castle and its people—how merchants supplied goods, how craftsmen passed down their techniques, and how farmers delivered their harvests to the dining table. The Nagoya metropolitan area has preserved several representative castle town settlements, each developing unique food culture and traditional crafts, making them the most worthwhile material for in-depth tourism exploration today.
Why Castle Towns Are Ideal for In-Depth Tourism
The greatest value of castle towns lies in their "functionality." The castle was the center of power, and naturally attracted various industries around it to meet the needs of the daimyō and castle town residents: sake brewing, soy sauce, textiles, ceramics, and woodworking. After centuries of competition and淘汰, what remained are the so-called "local industries"—crafts and flavors that can only be found in that particular location, with no second place in all of Japan.
Take the Owari region where Nagoya is located as an example: from Kiyosu, Oda Nobunaga's stronghold in the 16th century, to Inuyama, which continued to develop during the Edo period, and to Okazaki, which flourished after the Meiji Restoration due to the railway, each developed different industrial axes. When you walk through these castle towns, what you eat, taste, and buy are local-only experiences that cannot be replicated in any other city.
Recommended Destinations: Food and Crafts at the Three Major Owari Castle Towns
Inuyama: Castle Town Sweets at the Starting Point of the Kiso Road
Inuyama City is located north of Nagoya and serves as the gateway to the Nakasendō in the Kiso Valley. During the Edo period, this area flourished as the castle town of Inuyama Castle (the existing tenshu was rebuilt in 1932, though the underground stone walls are original), and developed a complete traveler service industry due to the post station system. Today, the core of Inuyama tourism is not the castle itself, but strolling through the traditional streets of Castle Town Suji and experiencing traditional wagashi.
The biggest difference between Inuyama wagashi and elsewhere is that it simultaneously absorbed influences from both Kyoto and Edo cuisines, plus the demands of Nakasendō travelers, developing a sweet aesthetics somewhere between the two. Representative items include "Inuyama Castle Town Manju"—thin-skinned with generous filling and moderate sweetness, completely different from the main Nagoya lineage of jujube manju. The confectionery shops on both sides of the castle town main street still maintain the front-store-back-factory operation model to this day, where you can watch masters working at the steaming baskets, and purchases can be requested in souvenir-ready packaging.
Beyond sweets, Inuyama's washoku cuisine (a local version based on kaiseki) is also a worthwhile experience option. The Inuyama area became a gathering place for literati during the Meiji era due to the railway connecting Tokyo and Kyoto, leaving behind ryōtei culture. Today, some shops still offer course meals centered on local ingredients.
Kiyosu: Where Nobunaga's Dream Began
Kiyosu Town is located between Nagoya and Ichinomiya, about a 15-minute walk from JR Kiyosu Castle Station. This castle town holds an extremely high historical status—when the Incident at Honnō-ji occurred in 1582, Oda Nobunaga's stronghold was actually Kiyosu Castle, not Azuchi Castle as most people mistakenly believe. After the incident, Toyotomi Hideyoshi convened the Kiyosu Conference at Kiyosu, laying the foundation for Hideyoshi's later unification of Japan.
Today's Kiyosu castle town is small in scale but has preserved several merchant districts from the Edo to Meiji periods. It's worth noting that the local snack "Kiyosu Goshiki Dango" (Kiyosu Five-Color Dango) is a limited edition product that can only be purchased in Kiyosu. Composed of five-colored rice dumplings, each representing one of the five grains, it's a traditional food reportedly made by locals during festival periods. Additionally, Kiyosu is an important miso-producing area in the Owari region. There's still a miso shop on the street that坚持使用木桶发酵 (insists on wooden barrel fermentation) called "Yamada Miso," offering on-site tastings. The cedar fermentation barrels inside the shop are over 50 years old—a quite rare commitment in today's mass-produced miso industry.
Kiyosu Castle's tenshu is a reinforced concrete structure rebuilt in 1989, with the interior converted into a local history museum. However, the surrounding castle town plaza and moat scenery are quite nice. Autumn castle town walking tours held during the Kiyosu Textile Festival are quite popular with local families.
Sakae & Yaba-cho: Evolution of Modern Castle Town Cuisine
If you think castle towns must feature ancient streetscapes, think again. The Ōsu and Sakae areas in central Nagoya were the "shitamachi" (lower town) of castle towns during the Edo period—commercial districts where commoners and merchants lived. In the Reiwa era, this has evolved into another form of castle town: a ultra-dense gourmet area combining traditional food culture with modern street food. \n
"Miso Katsu" (miso cutlet) in the Yaba-cho area is the most representative modern castle town cuisine in the area. After WWII ended in 1945, a local shop combined Nagoya's characteristic Hatchō Miso with fried pork cutlet, creating this richly flavored regional dish. Today, Yaba-cho and its surroundings gather over 20 katsu shops, with price ranges between ¥1,200 and ¥1,800 (lunch sets). Each shop has different claims regarding miso sauce sweetness, breading crispness, and meat marbling, forming a small-scale gourmet competition market.
In the same area, you can also find the original store of chicken wing specialty shop "Sekai no Yamachan," a process of elevating Nagoya chicken wing culture into a nationally recognized brand that itself serves as a modern case study of castle town food evolution.
Okazaki: Tokugawa Ieyasu and Hatchō Miso Castle Town
Okazaki City holds a special historical status—it is Tokugawa Ieyasu's birthplace, as well as the hometown of Hatchō Miso. From the east exit of JR Okazaki Station, take a bus toward Okazaki Park; after about 20 minutes, you can reach the castle town area centered on Okazaki Castle.
What makes Hatchō Miso special is its aging time and flavor. Made by fermenting soybeans and rice koji, the standard long-aged variety requires at least two years, during which artisans regularly stir with wooden sticks to check fermentation status. The final product is dark brown with a thick, sticky texture, completely different from the common light-colored red miso, making it the core ingredient of Okazaki regional cuisine.
In the castle town area, you can see several miso breweries that adhere to traditional production methods. Among them, "Maruya Hatchō Miso" offers factory tours (free admission, groups require reservation), where you can get up close to view the massive array of cedar barrels. After the tour, it's recommended to purchase the limited-edition whole soybean miso at the direct sales counter—this variety with complete soybean texture and concentrated saltiness is the proper way to experience it, available only at the production site.
Practical Information
For visiting the castle towns mentioned above, it's recommended to use Nagoya as your base and travel using rail passes. The JR Kansai Wide Area & Chubu Area Pass (5-day pass at ¥26,660) is expensive but covers Kiyosu and Okazaki, suitable for in-depth travelers with ample time. For those with limited time, purchasing the ¥700 TRANSIT PASS (applicable to all Nagoya Railroad lines) allows unlimited rides for one day, keeping transportation costs for round trips to Inuyama or Kiyosu within reasonable ranges.
Most tour facilities at castle towns are free or charge nominal fees (¥300-¥500). Dining costs vary by choice: traditional sweets ¥150-¥400, miso course meals ¥1,500-¥3,000, luxurious kaiseki ¥6,000-¥12,000. There's no need to have full meals at every stop—choosing one representative snack and eating while walking better matches the pace of castle town strolls.
Regarding business hours: traditional workshops and tour facilities typically close around 4 to 5 PM, while restaurants stay open until around 8 PM. It's recommended to arrive at castle towns in the morning, complete tours and shopping first, then arrange meals in the afternoon.
Travel Tips
The core of castle town strolling is "slow" and "try"—slow your pace and sample at every shop. Castle towns in the Nagoya metropolitan area are generally small in scale; 2 to 3 hours are sufficient to complete core walking routes, but the information density gained is extremely high. If your itinerary includes multiple castle towns, it's recommended to allocate "eat" and "buy" experiences to different locations: for example, focus on wagashi tasting in Inuyama, while making miso shopping the main theme in Kiyosu, avoiding homogenized repetitive experiences.
Another suggestion is to avoid weekend afternoons—castle town tourist crowds tend to concentrate between 2 and 4 PM on weekends. Arriving before 10 AM or choosing a weekday visit allows for a more从容 (leisurely) pace of exploration, and makes it easier to interact with local shop owners and hear local stories that aren't written in guidebooks.
