Three themed pop-up stores, exclusive merchandise, and collectible postcards await fans from September 15 to October 20.
Hong Kong, September 2026 – Sushiro Hong Kong has announced its first-ever collaboration with Opanchu Usagi, the internationally adored Japanese character created by artist KAWAISOUNI!, known affectionately among fans as “Panties Rabbit.” From September 15 to October 20, 2026, the partnership will transform three Sushiro locations into immersive themed dining spaces, introduce a series of limited-edition menu items, and offer exclusive collectible merchandise—including a Hong Kong-exclusive postcard set.
Three Themed Stores Bring Opanchu Usagi to Life
Three Sushiro outlets will be fully redesigned to reflect the quirky, bittersweet world of Opanchu Usagi—a character famous for blending cuteness with misfortune. The participating branches are:
- Causeway Bay Plaza 2 Store – 3A, 3/F, Causeway Bay Plaza 2, 463-483 Lockhart Road, Causeway Bay
- Mong Kok Store – Basement, King’s Centre, 628 Nathan Road, Mong Kok
- Tin Shui Wai T Town Store – Shop SG17, G/F, T Town South, 30 Tin Wah Road, Tin Shui Wai
Each location will feature oversized photo walls, character standees, and themed table decorations. Notably, three Hong Kong-exclusive comic strips have been printed on the walls, incorporating local lifestyle details to offer a healing, relatable experience for fans.
Special Menu Items Inspired by the Character
Sushiro is launching four limited-edition dishes and drinks available across all Hong Kong branches (excluding the Sham Shui Po West Kowloon Centre and Wan Chai Emperor Group Centre locations):
- Tuna New Autumn Persimmon Rice Ball with Squid (HK$17) – The pink rice ball mimics the character’s body, while the white squid represents Opanchu Usagi’s signature “panties.”
- Grilled Basil Duo (Salmon & Shrimp) (HK$17) – Topped with classic cheese and aromatic basil mayonnaise, then grilled.
- Crispy Caramel Sweet Potato with Vanilla Ice Cream (HK$34) – A hot-and-cold dessert combining torched sugar-coated sweet potato with creamy vanilla ice cream.
- Collaboration Drink Set (HK$99) – Includes multiple beverages and unlocks a limited-edition plush charm.

- Collaboration Insert Cards (6 designs, random) – free with Tuna New Autumn Persimmon Rice Ball with Squid
- Acrylic Keychains (6 designs, random)
- Plush Charms (4 designs, random), including Hong Kong-exclusive styles
Collectible Postcard Redemption Program
From September 15 to October 20, customers who collect five insert cards (any design) by ordering the specified collaboration dishes can redeem one Hong Kong-exclusive Opanchu Usagi postcard (3 designs, random) at any participating Sushiro branch.

Broader Impact and Next Steps
This collaboration signals a growing trend among Hong Kong’s F&B sector to tap into the emotional resonance of Japanese pop culture icons—especially those with quirky, relatable backstories. Opanchu Usagi’s appeal lies in its “pitiful yet adorable” narrative, which resonates strongly with young adults navigating modern life’s ups and downs.
