Last researched 2 November 2026 · 5 sources

Tokyo glassware maker best known for its V60 coffee dripper.

There's no proof Hario pays more than the legal minimum, which in China is below a living wage, and it has no full independent audit.

Why it's graded Lacks transparency

Not met: Meets 2 of 6 Good requirements.
Holds the grade back: It doesn't show that workers are paid a living wage, and isn't certified as working towards one. On Track needs at least one of these.
It isn't Harm on record, because there's no serious confirmed problem on its record.
Lacks transparency is still a poor grade: in supply chains like this, workers who can't be seen to be treated fairly are usually underpaid or unprotected.
