Since we first began our relationship with THE SUPERIOR LABOR in 2020, there has been a quiet understanding between our two brands; a shared belief that the objects we live with everyday matter deeply. They inspire us to slow down, pay attention, and participate more fully in our own lives.

Yoseka exists to bring people closer to stationery. To create a place where curiosity grows, creativity feels accessible and everyday tools become companions for thinking, creating and remembering.

The Superior Labor has long embodied those same values through craftsmanship rooted in patience, integrity and honest labor. Founder Makoto’s journey, from spending his childhood using the metalworking machines in his grandfather's workshop to auto repair to discovering leather craftsmanship when he lived in the US, lives inside every product from TSL. Their work carries the feeling of hands that understand materials, time and care.

UNION is the meeting point of these philosophies.

Created collaboratively by Yoseka Stationery and The Superior Labor, UNION is the beginning of a partnership that will continue to evolve over the coming years. This first collection debuts at Stationery Fest Summer 2026, where Makoto, Yoshimi, and the TSL team will join Yoseka to celebrate the release together with the stationery community that brought the two brands together in the first place.
