About THE INK

THE INK

A welcoming studio for clients. A workspace where artists can focus on their craft.
A store where you can examine tools in person. THE INK brings all three together in one studio and showroom.

Where people, tools,
and place come together.

Clients visit. Artists gather. Guest artists come and go, and tools can be tried in person. The more people connect in one place, the more opportunities there are to encounter great work.

THE INK aims to be a place where everyone connected to tattooing can come together naturally. We are gradually opening up an industry that has often remained closed off.

A studio created
by a tattoo supply company.

FLAG Tattoo Supply is a tattoo supplier founded in 2015. For around a decade, it has supported artists across Japan through its products and services.

THE INK gives that work a physical home. From selecting tools to organizing the studio floor, everything is backed by years of hands-on experience as a supplier.
