"@cosme STORE TSUTAYA Hakodate" to Undergo First Full Renovation, Reopening in November 2026

Istyle Inc. (President and CEO: So Endo), a consolidated subsidiary, announces that its "@cosme STORE TSUTAYA Hakodate" store will reopen after renovations in November 2026.

Opened in 2016, "@cosme STORE TSUTAYA Hakodate" was the first "Tsutaya Books" store to open nationwide and is located within "Hakodate Tsutaya Books," a community spot frequented by citizens of all ages, from students to seniors. The store has offered a wide lineup of popular products trending on @cosme reviews and provided detailed, personalized consultations to each customer. Thanks to strong support for its consultation services, the store has become a community-based establishment, sustained by many customers.

In this renovation, the store area will be expanded from the previous 80 tsubo to 95 tsubo. The in-store environment will be significantly updated, transforming into a space where customers can enjoy both self-service shopping for trying products and personalized consultations. We aim to become a store that is even more loved by the citizens of Hakodate, allowing them to discover their "destiny cosmetics" while experiencing the latest cosmetic trends utilizing @cosme's data.

Details about the store will be announced again once they are finalized. Please stay tuned.
