Tochio: Niigata's Giant Aburage Town & Local Street Food Guide

What Makes Tochio Aburage Different

Most visitors to Japan encounter aburage (油揚げ) as thin, flat pouches of fried tofu — the kind stuffed into inari sushi or sliced into miso soup. Tochio aburage (栃尾油揚げ) is something else entirely. Each piece measures approximately 20 cm long, 10 cm wide, and 3 cm thick — a golden slab of tofu with a crispy exterior and a fluffy, almost custard-like interior.

Tochio is a small district in northeastern Nagaoka city, Niigata Prefecture, where this oversized aburage has been produced for generations. According to the Nagaoka Tourism Guide, the tradition likely originated in the Edo period, possibly as a sake snack for horse traders or as a souvenir sold near local shrines.

The town has over ten tofu shops producing their own versions, each with subtle differences in texture and flavor. For travelers exploring Niigata's food culture or the broader Echigo region traditions, Tochio offers one of the most distinctive and affordable culinary experiences in the prefecture.

How Tochio Aburage Is Made: The Double-Fry Method

The dramatic size and texture of Tochio aburage comes from a double-frying technique. According to the Nagaoka Tourism Guide, firm tofu is first deep-fried at a low temperature of approximately 110°C for 15-20 minutes. This slow fry causes the tofu to expand dramatically — puffing up to several times its original thickness as moisture inside turns to steam.

The expanded tofu is then fried a second time at approximately 175°C for a few minutes, which crisps the outer skin to a golden crunch while keeping the inside airy and soft. The result is nothing like standard aburage — it is closer in texture to a savory doughnut than a tofu product.

Many shops in Tochio use Enrei (エンレイ), a local Niigata soybean variety prized for its high protein and sugar content. The combination of local soybeans and the double-fry method is what gives Tochio aburage its distinctive character.

Where to Eat: Tofu Shops and How to Order

Mamesen: Traditional Method with Local Soybeans

Mamesen (豆撰) is one of Tochio's most established tofu shops, using local Enrei soybeans and a traditional fresh-squeeze method for their soymilk. According to food guides, the shop is open approximately 9:00-18:00 and closed for one week after Obon and around the new year. A single piece of aburage costs roughly ¥300-500 (~$2-3.30).

Mamesen is a good starting point for first-time visitors — their aburage represents the classic Tochio style, and you can watch the production process in the shop.

Walking the Tochio Aburage Shop Map

Tochio has more than ten tofu shops, each producing aburage with slightly different recipes, textures, and toppings. A local aburage map is available at shops and the station area, marking all the producers with their specialties.

Many visitors on food blogs recommend visiting at least 2-3 shops to compare. Prices at most shops range from ¥200-400 (~$1.30-2.70) per piece for fresh aburage, with toppings and special versions costing slightly more. A satisfying tasting tour of several shops costs well under ¥1,000 (~$7).

Shop hours are generally 9:00-17:00, though some close irregularly (Wednesdays are common). Morning visits are recommended to catch freshly fried batches — by afternoon, some shops may have sold out for the day.

How to Eat Tochio Aburage

Fresh From the Fryer: Dekitate Style

The ideal way to eat Tochio aburage is dekitate (出来立て) — fresh from the fryer, still hot and crackling. Shops typically slice the aburage down the middle, revealing the fluffy interior, and serve it with a small dish of soy sauce or grated ginger.

Eating it hot captures the contrast between the crispy exterior and the soft, almost molten interior — a texture that is difficult to replicate with packaged versions. If you are buying to take home, shops sell vacuum-packed aburage that keeps for about 5 days refrigerated. Reheat in a frying pan (not a microwave) to restore some of the crispness.

Toppings and Variations

While purists eat their aburage with just soy sauce and ginger, shops offer various toppings:

• Mentai mayo: spicy cod roe with mayonnaise — a modern favorite
• Natto: fermented soybeans stuffed inside the aburage
• Negi (green onion): simple and traditional
• Miso glaze: grilled with miso paste for a smoky-sweet flavor

Some shops also grill the aburage over charcoal, adding a smoky dimension to the crispy skin. These grilled versions are particularly good with sake — a pairing that locals have enjoyed since the Edo period.

Getting to Tochio From Nagaoka and Beyond

Tochio is part of Nagaoka city, located in the northeastern outskirts. It is an easy side trip from Nagaoka Station.

Nagaoka IC → Tochio by car	~20 min (Route 17)	Parking at shops
Niigata Station → Nagaoka → Tochio	~40-50 min total	Shinkansen + local train

From Tochio Station, the main tofu shop area is walkable. The district is compact enough to cover on foot in a morning or afternoon.

Tochio combines naturally with a visit to Nagaoka city — take the morning to visit tofu shops in Tochio, then return to Nagaoka for the afternoon. During the August fireworks festival, Tochio makes a pleasant morning excursion before the evening spectacle.
