ACE Corporation (headquarters: Shibuya-ku, Tokyo; President: Hiroaki Morishita), a bag manufacturer, will hold the first pattern order fair featuring the luxury line "J5 Collection" of its Japanese-made travel bag brand "PROTECA" and the brand "OHBA/Ōkyō Seikatsu" of the long-established luxury leather goods maison Ōkyō Seikatsu Kaban. The fair will take place at "Isetan Suitcase" on the basement floor 1 of Isetan Kaikan from Wednesday, June 10 to Thursday, June 25, 2026.

Combine leather parts in 16 colors, imbued with the craftsmanship of Ōkyō Seikatsu Kaban, with luggage that reflects Japanese aesthetics to create a one-of-a-kind piece.

"J5 Collection" is a luxury line developed by the Japanese travel bag brand "PROTECA." The order target "SHISUI-F" is a Japanese-made luggage inspired by a book box for storing precious items, with a dignified presence.

At this fair, handles and name tags made of German shrink calf leather by "OHBA/Ōkyō Seikatsu" can be selected from 16 colors. Adding the rich expression of leather and the warmth of handiwork to the functional beauty of the luggage, we propose a piece that deepens attachment with every trip.
