A collaboration café between the original TV anime “HIGH CARD” and the specialty tea shop Oshiad will be held at three locations—Harajuku, Daikanyama, and Kanazawa—from September 18 to October 12, 2026. The event will feature herbal tea sodas, mocktails, and tea-inspired snacks inspired by the characters, and customers who place orders or make reservations will receive coasters and illustrated cards.
