Furumachi Onsen (古町温泉)

Introduction: The Vibrant Heart of the 1,200-Year-Old Resort

As the largest and most commercially vibrant district in the valley, Furumachi Onsen (古町温泉) serves as the central “Base Camp” for all Shiobara explorations. [1, 25] This district is defined by the sweeping arcs of the Hoki River, a bustling main street filled with traditional confectionery shops, and a skyline where historic architecture meets modern resort luxury.

For the international traveler, Furumachi offers the most diverse range of facilities and accessibility. It is the home of Yuppo no Sato—Japan’s largest footbath facility—and the Shiobara Monogatarikan museum. [2, 26] Whether you are “onsen hopping” to experience the seven different water colors of Shiobara or shopping for “Toteyaki” snacks along the riverfront, Furumachi is the indispensable starting point for any Tochigi wellness journey. [27, 28]

Key Information Table

The Healing Waters: The “Metasilicic Acid” Fountain

Furumachi’s waters are scientifically prized for their high stability and metasilicic acid (silica) content, which often exceeds 100mg per liter. Metasilicic acid is a natural beauty component that stimulates skin metabolism and smooths the epidermis, earning Furumachi the reputation of a “Bijin-no-yu” (Hot Water for Beautiful Skin). [32, 4]

The district manages 28 distinct hot spring sources, ranging from 40°C to 69°C. [25] This volume allows for the creation of unique thermal experiences, such as the 60-meter circular footbath at Yuppo no Sato, where the floor is studded with stones that provide a reflexology effect as you walk through the mineral-rich waters. [33, 26]

Must-Visit Highlights: Footbaths and Bridges

Yuppo no Sato (湯っ歩の里): A circular forest park featuring one of Japan’s longest footbaths (60 meters). [26] It is constructed from aromatic Hinoki cypress and offers beautiful garden views that shift from snowy landscapes in winter to lush greens in summer. [2, 26]

Shiobara Monogatarikan: This riverside facility acts as the town’s visitor center and history museum. [40, 25] Located behind the building is the Kurenai-no-Tsuribashi (Red Suspension Bridge), arguably the most iconic photography spot in the valley during the autumn foliage peak. [29, 41]

Local Gastronomy & Souvenirs: The “Toteyaki” Tour

Toteyaki (とて焼き): A unique Shiobara snack—a thick, castella-batter crepe filled with local raw milk products or savory toppings like grilled pork. [42, 43] Furumachi has over 10 shops offering their own original versions.

Highland Daikon: Shiobara Highland Daikon radishes are famous for their extreme sweetness, a result of the cold mountain nights. Try the local “Takuan” (pickled radish) served at every ryokan breakfast. [42, 44]

Vegan & Vegetarian Options: The Cafe Restaurant Lamp (inside the museum) offers a special Meiji-inspired vegetable set and sweets loved by the author Natsume Soseki. [45, 46] For those staying at Kousunso, specific vegetable-only Kaiseki can be provided with a 3-day notice.

Practical Travel Tips for 2025-2026

• Tattoo Policy: Large resorts like Hotel New Shiobara allow tattoos if they are smaller than 6.5cm x 10.5cm and can be covered with the facility’s official sticker. [47, 48] Small traditional ryokans in Furumachi often ignore small tattoos or suggest using the private baths. [19, 49]
• Connectivity & Cash: Furumachi is the most tech-friendly district; credit cards are accepted in major hotels, but the “Toteyaki” street vendors are strictly cash-only (JPY).
• Digital Guide: Download the “Digital Map of Nasushiobara” for real-time bus tracking and English menus at local eateries. [50]

Safety & Manners

Winter Footwear: The “Red Suspension Bridge” and the wooden decks at Yuppo no Sato can be extremely slippery when frosted. Crampons or high-traction boots are recommended for the 2025-2026 winter season. [51, 52] Respect the Queue: Soup Yakisoba shops like Kobaya can have 20-person queues on weekends; always sign the waiting board and wait in your car or at the designated spot. [19, 53]
