The Legacy of a Century-Old Fish Shop: 'Uo to Sake Beck' Opens in Ikebukuro

On May 15, 2026, a remarkable culinary venture will debut in Ikebukuro, Tokyo, as 'Uo to Sake Beck' opens its doors just a two-minute walk from Ikebukuro Station's west exit. This establishment is a new type of fish tavern that carries on the wisdom and spirit of 'Uohatsu,' a cherished fishmonger that has been beloved in Kichijoji for approximately 100 years. With a selection of the freshest fish prepared with unique craftsmanship, the restaurant promises an enticing combination of fish and local sake, offering a vibrant dining experience.

A Century of Expertise in Ikebukuro

Founded nearly a century ago in Kichijoji, 'Uohatsu' evolved, and by 2020 had transformed into 'Musashisakai Osakana Yas-san,' continuing to serve the community faithfully. Since its incorporation into Mostfun in 2024, this restaurant has maintained its commitment to quality and customer satisfaction, holding onto the traditional values that define its legacy. The owner personally visits Tsukiji Market each morning, carefully selecting the finest fish to be directly delivered to the restaurant. Chefs then meticulously craft these ingredients into exquisite dishes served to delighted customers.

The Signature 'Shidaime Okumori'

The signature dish 'Shidaime Okumori,' which has inherited the essence of 100 years of fish preparation, offers a wonderful array of thick-cut fish slices, embodying the restaurant's philosophy that the true quality of fish comes through in its texture. Priced at 1,980 yen (tax included) per serving, this dish highlights bold cuts of the day's best fish, ensuring a satisfying experience for each patron.

Accompanying the seafood offerings, the restaurant features two exclusive soy sauces developed especially for pairing with sashimi: a sharp, dry soy sauce and a rich, sweet tamari. Furthermore, they source high-quality ingredients, such as 'Namarashio' from Hokkaido and fresh vegetables harvested daily from Chiba.

Featured Delicacies

- Polite Potato Salad (780 yen, tax included): This dish combines half-boiled eggs mixed with special sour cream to enhance the natural sweetness of the potatoes, making it a delightful treat.
- Whole Onion Oden (680 yen, tax included): Slow-cooked Awaji onions soaked in savory broth result in this sumptuous, melt-in-your-mouth oden.

Selecting Sake by Today's Mood

'Uo to Sake Beck' stands out by offering a selection of sake tailored to match the customer's current mood. Rather than focusing solely on flavor, patrons can choose from a daily list of 16 different sake options based on how they feel. For instance, whether you're looking to elevate a regular day or are in search of perfectly paired fish, the establishment has something for everyone.

Cozy Ambiance with a Unique Layout

The restaurant's unique three-story layout features a mid-level area where guests can remove their shoes and unwind in a homely atmosphere. This space encourages relaxed conversations, allowing diners to enjoy their time together without pretense, reminiscent of a hidden retreat.
