Heritage "Kushiro Soba" and Freshly Crafted Sushi

Opened in April 2026 as the second location of "Sobadokoro Marui Yamasachi," which carries on the food culture of "Kushiro, the City of Soba," this restaurant has already gained support among local diners. Its distinctive Kushiro-style soba makes it a fitting choice for lunch while traveling.

A Blissful Taste of Dashi-Rich Soba and Fresh Seafood

"Soba to Sushi Marui Yamasachi Betsuan" brings together smooth, easy-to-eat soba and sushi made with seafood selected for freshness in a bright, comfortable interior with modern Japanese design. The signature noodles are traditional "Kushiro soba," distinguished by their vivid green color from added chlorella, while the local specialty "Muryoju Soba" is another featured choice for visitors. In addition to sushi prepared by the chef, seafood rice bowls and freshly fried tempura are also well received by local diners.

"Crispy Tempura and Soba" in the "Tenzaru"

The featured "Tenzaru" pairs traditional "Kushiro soba," known for its firm texture and smooth finish, with freshly fried, crisp tempura, creating a distinctive contrast in texture. The generously sized shrimp tempura is especially satisfying, with a light, crisp coating and springy shrimp. "Soba to Sushi Marui Yamasachi Betsuan" carries on the tradition of "Sobadokoro Edohigashi," one of the notable restaurants in "Kushiro, the City of Soba," and serves vivid green "Kushiro soba" made with chlorella powder. The restaurant is a strong choice for both local residents and visitors from Japan and abroad.

  • Rich Green Hues with Striking Visual Appeal

    Traditional "Kushiro soba," found throughout the Kushiro area, is distinguished by its vivid, deep green color. The noodles contain chlorella, a type of single-celled green algae found mainly in lakes, marshes, and rivers, known as one of the earliest forms of plant life on Earth and containing a balanced range of nutrients such as vitamins and minerals.

"Eight-Piece Chef's Choice Sushi"

Sushi prepared by the chef with seafood distinctive to Hokkaido has become as well received as the firm, smooth "Kushiro soba." Freshness is a priority, with toppings changing according to the day's selection in two options: "Chef's Choice Eight-Piece Sushi" and "Chef's Choice Five-Piece Sushi." Wasabi can be omitted, making the sushi suitable for diners of all ages. Many diners order a sushi and soba set, with an additional charge allowing a choice of small-size "Kokake Soba," "Kohiya Soba," "Kokashiwa," or "Komuryoju."

Must-try signature dish

  • Three "Dipping Soba" Varieties Paired with a Special House Broth

    The "Tsuke Soba" lineup includes three varieties: "Tori Zaru (chicken)," "Kawa Zaru (chicken skin)," and "Kamo Zaru (duck)," each carefully balanced with its own distinctive dipping sauce. After boiling, the soba is chilled in cold water to highlight its firm texture and smooth finish. The natural aroma and flavor of the soba unfold with each bite, reflecting the skill of an experienced soba craftsman.

  • Two "Inari Sushi" with a Simple, Gentle Flavor

    Inari sushi features deep-fried tofu pockets simmered in a sweet-savory dashi and filled with mildly sweet vinegared rice. The rich umami of the dashi and gentle sweetness spread through each bite, blending harmoniously with the rice for a simple, nostalgic flavor. It pairs well with soba and makes a fitting additional dish when something extra is wanted.

Restaurant highlights

  • Freshly fried with a light, crisp coating

    Tempura Fried in 100% Pure Sesame Oil

    The tempura is fried in pure sesame oil made from 100% sesame, known for its resistance to oxidation and stability at high temperatures. The fragrant character of sesame brings out the natural umami and sweetness of the ingredients while pairing especially well with soba. Frying quickly at high heat creates a crisp texture, while the well-drained oil keeps the tempura light.

  • Authentic sushi crafted without compromise

    Sushi Rice Made with a Signature Red and Rice Vinegar Blend

    Sushi rice prepared with the restaurant's original blend of vinegars further enhances the flavor of seasonal seafood. The blend combines rich, full-bodied red vinegar made from sake lees with gently sweet rice vinegar, balancing the deep umami of red vinegar with the mellow acidity of rice vinegar.
