■ A highly popular summer specialty menu that we receive many inquiries about every year regarding its launch date!

Eastone Co., Ltd. (Headquarters: Sapporo, Hokkaido; President: Yasumasa Oyama), which operates 47 restaurants including 'Yakitori Dining Itadaki Kokko-chan', 'Hokkaido Italian Mia Bocca', and 'Hokkaido Wheat Fresh Pasta Mugi to Tamago' in the Tohoku and Kanto regions, will launch its hugely popular annual summer specialty, 'Hokkaido Saltwater Sea Urchin Cold Spaghetti', at all 'Hokkaido Italian Mia Bocca' locations starting Monday, June 1, 2026.

'Hokkaido Saltwater Sea Urchin Cold Spaghetti' is a masterpiece that features delicate capellini pasta tossed in a flavorful sauce of scallop and kelp dashi, luxuriously topped with Hokkaido saltwater sea urchin. While many sea urchin spaghetti dishes generally use alum, our restaurant uses fresh saltwater sea urchin delivered from Hokkaido. Its luxurious taste, which maximizes its freshness, continues to captivate sea urchin lovers. It is a summer tradition that has even turned many people who disliked sea urchin into fans after eating this menu.

This year again, we generously use rare saltwater sea urchin shipped directly from Hokkaido, and combined the umami dashi of scallops and kelp with ultra-thin capellini to create a highly aromatic and luxurious cold pasta.

A massive hit menu with over 300,000 servings sold across sister stores! The appeal of Hokkaido Saltwater Sea Urchin Cold Spaghetti that masters an adult taste.

Sales began in June 2006 for the dish affectionately known as 'Unispa'. To protect the freshness and taste of the freshly caught sea urchin extracted from the shell, we use 'Hokkaido purple sea urchin' and ship it directly from Hokkaido to each store while still immersed in saltwater. Because sea urchin meat is very delicate and crumbles easily, alum is often used to maintain its shape. However, the sea urchin used at Mia Bocca does not use alum. Not only does it have the original sweetness and melting texture of the golden-shining sea urchin, but the scent of the ocean that spreads the moment you put it in your mouth, along with its delicate and elegant taste, offers supreme emotion.

Another reason that enhances the umami of Unispa

The secret ingredients that further enhance the umami of the saltwater sea urchin are 'kelp dashi' and 'scallop dashi'. This is a flavor we finally arrived at after testing compatibility with all kinds of dashi and changing the blend many times.
