Nasukarasuyama's culinary identity reflects centuries of living in harmony with the Yamizo Mountains and the clear Naka River. The city's food culture emerged from its position as a prosperous castle town and Edo-era transportation hub, where mountain foraging, river fishing, and agricultural traditions converged to create a distinctive regional cuisine. Today, visitors can experience authentic mountain vegetables foraged from surrounding peaks, sweetfish caught using traditional bamboo fish traps, handmade buckwheat noodles from local harvests, and sake aged in a unique WWII-era cave brewery. 🔗

The food traditions here emphasize seasonality, simplicity of preparation to highlight natural flavors, and sustainable harvesting practices passed down through generations. Unlike tourist-focused culinary scenes, Nasukarasuyama maintains authentic working food culture where locals still forage for spring vegetables, operate traditional fish traps, and patronize century-old sake breweries.

Mountain Vegetables (Sansai)

Cultural Context

The Yamizo Mountains surrounding Nasukarasuyama provide rich foraging grounds for wild mountain vegetables called sansai. The region yields around 50 different types of edible wild plants, making this a significant aspect of local food culture. These vegetables represent the "wild taste of spring" - slightly bitter, earthy flavors that Japanese tradition holds will awaken the body after winter. 🔗

Sansai originally referred to plants foraged in the wild rather than cultivated in fields, though some varieties like warabi (bracken) have been successfully cultivated. Sansai foraging reflects gratitude and respect for nature, aligning with Japanese cultural values of sustainability. The practice connects local cuisine to Buddhist vegetarian traditions (shojin ryori). 🔗

Key Varieties Found in the Region

The Tochigi region, including Nasukarasuyama, produces several prized sansai varieties:

• Tara no Me (angelica tree sprouts) - Called the "king of sansai" for its delicate flavor
• Fukinotou (butterbur sprouts) - One of the first spring vegetables to appear
• Yomogi (Japanese mugwort) - Used in traditional sweets and teas
• Asatsuki (wild chives) - Mild onion flavor
• Kanzou (daylily shoots) - Sweet and tender when young
• Nazuna (shepherd's purse) - Traditional spring green
• Udo (mountain asparagus) - Tochigi ranks among top producers in Japan 🔗

Preparation Methods

Sansai are typically prepared simply to highlight their distinctive bitter, earthy taste:

• Tempura - Oil softens the astringency common to these plants 🔗
• Aemono - Blanched and dressed with sesame or miso
• Simmered in dashi - Gentle cooking preserves delicate flavors
• Pickles - Traditional preservation method used for centuries

Most sansai contain higher amounts of vitamins, minerals, and dietary fiber than cultivated vegetables. The unique bitterness comes from plant-based alkaloids and polyphenols thought to detoxify the body and promote metabolism. 🔗

Seasonal Availability & Where to Experience

Peak Season: March-May - Sansai typically appear as the snow melts and are only available for a few months, making them a limited-time seasonal treasure. Spring is the optimal time to visit Nasukarasuyama for authentic mountain vegetable cuisine.

Agricultural Direct Sales Offices (農産物直売所) - Six farmers' markets throughout the city sell fresh sansai during spring:

• Yatsugashira Vegetable Direct Sales Office - Fresh seasonal vegetables
• Koya Agricultural Product Direct Sales Office - Homemade goods and mountain vegetables

These markets provide direct access to foraged and locally grown produce, often with producers present to discuss their harvest.

River Fish Traditions

Cultural Significance

The clear Naka River (那珂川) flowing through Nasukarasuyama has shaped local food culture for centuries. The river provides one of Japan's finest environments for ayu (sweetfish), making river fish a defining element of regional cuisine. Traditional fishing methods, particularly the yana (bamboo fish traps), represent cultural heritage passed down through generations. 🔗

Ayu (Sweetfish) - The Star Delicacy

Ayu are prized throughout Japan, but Nasukarasuyama ranks among the country's top locations for this delicacy. The sweetfish earned its name from its distinctive flavor - described as having "melon and cucumber aromas" with sweetly flavored flesh. The Japanese call it kougyo (aromatic fish) for its refreshing, prized scent. 🔗

Seasonal Context:

• Fishing Season Opens: June 1st - Summer is the peak season for fresh ayu
• Late Summer/Autumn (August-October) - Yana season when fish migrate downstream

Traditional Preparation: Ayu are typically grilled whole on skewers with salt (shioyaki) over charcoal, with their bodies folded in a distinctive wave-like "swimming" shape. This simple preparation preserves the natural flavor and aromatic qualities. 🔗

Yana (Traditional Fish Traps)

Yana are large-scale bamboo structures set in the river to catch ayu as they migrate downstream. Visiting a yana is a quintessential local experience, combining fishing heritage with dining. These traditional traps represent sustainable fishing methods that have been used for centuries.

Recommended Yana Restaurants:

Visitor Experience

Yana restaurants offer an immersive cultural experience beyond just dining.

The combination of natural beauty, cultural heritage, and exceptional cuisine makes yana dining a highlight of visiting Nasukarasuyama during summer and autumn.

Local Sake Culture - Shimazaki Brewery

The Cave Brewery

Nasukarasuyama's sake scene centers entirely on one exceptional brewery with 175 years of history and a unique aging facility.

History & Heritage: Founded in 1849 by Hikobe Shimazaki during the Edo period, the brewery has operated continuously for 175 years. The second-generation proprietor Kumakichi, a sumo wrestling enthusiast, named the brand Azumarikishi (東力士) meaning "Sumo of the East." 🔗

The Unique Cave Aging Facility: Shimazaki is known worldwide as "The Cave Brewery" for its extraordinary aging storehouse - a 600-meter-long series of tunnels originally built near the end of WWII to construct combat vehicles underground. After the war, the brewery converted these tunnels into sake aging cellars. 🔗

• Environment: Complete darkness, untouched by sunlight
• Capacity: Approximately 100,000 bottles resting in the cave
• Aging: Specializes in long-aged daiginjo sake, beginning this focus in 1970

Award-Winning Sake: Uroko Yamahai Junmai Genshu (熟露枯 山廃純米原酒) won the Platinum Award at the French Sake Competition, earning international recognition. 🔗

Curry-Flavored Croquettes - Unique Local Specialty

The Local "Soul Food"

Nasukarasuyama has an unusual claim to culinary fame: curry-flavored croquettes (カレーコロッケ) as the default croquette style. This is so deeply embedded in local culture that when you order a croquette at butcher shops or restaurants in Nasukarasuyama, you receive a curry-flavored version rather than the standard beef or potato croquettes found elsewhere in Japan. 🔗

Local residents have expressed surprise upon traveling elsewhere and discovering that "regular" croquettes are typically white (without curry), highlighting how normalized this variation has become in Nasukarasuyama.

Historical Origins

While various theories exist, the most accepted explanation ties curry croquettes to Nasukarasuyama's prosperous history:

From the late Edo period through the early Showa period, Karasuyama prospered as a water transport hub along the Naka River. Goods like timber, paper, and wheat moved through the town via river barges. During this period, curry powder was among the exotic commodities handled by local merchants. 🔗

It's believed that locals added curry powder to croquettes as a symbol of modernity and Western influence - making everyday food more fashionable and exotic during Japan's period of rapid modernization in the Meiji and Taisho eras. The curry croquette became normalized over generations, evolving into the local standard.

Where to Purchase

Approximately four butcher shops in the city sell these specialty curry croquettes, each with distinct characteristics:

Ishihara Meat Shop (石原食肉店)

• Made fresh to order
• Served piping hot
• Traditional butcher shop atmosphere
• Located in central Nasukarasuyama 🔗

Daiwa Meat Shop (大輪精肉店)

• Another local butcher offering curry croquettes
• Each shop has its own recipe variations 🔗

Curry croquettes are sold at these butcher shops as takeaway items - perfect for a quick local snack while exploring the town. They represent "B-grade gourmet" (B級グルメ) - unpretentious, locally-loved comfort food rather than haute cuisine.

Cultural Significance

Nasukarasuyama's food culture exemplifies rural Japanese foodways rooted in seasonal rhythms and sustainable resource use. The reliance on foraged mountain vegetables and river fish demonstrates centuries of living harmoniously with the natural environment.

The yana fish traps represent significant cultural heritage - traditional, sustainable fishing methods passed through generations. These bamboo structures embody Japanese principles of working with nature rather than dominating it.

The evolution of unique local specialties like curry croquettes illustrates how regional cuisines develop through historical circumstances. Nasukarasuyama's position as a transportation crossroads made it receptive to new ingredients (curry powder) during Japan's modernization, leading to distinctive local adaptations of Western-influenced foods.

The continued production of handmade soba and traditionally-aged sake demonstrates deep respect for craftsmanship. These practices require skill, patience, and commitment to quality that transcends commercial efficiency - values central to Japanese artisanal food culture.

Finally, the food culture here remains authentically local rather than tourist-oriented. Residents still forage for spring vegetables, patronize century-old sake breweries, and consider curry croquettes their soul food. Visitors experience working food culture rather than staged culinary tourism.
