Our laboratory in Ginza
Every formula starts at the raw-material level — in-house.
Hanajirushi formulas are developed in our laboratory in Ginza, Tokyo. From choosing ingredients to designing each formula, we explore every possibility with care, aiming for skincare that is gentle on the skin and that you can feel working.
Because R&D, manufacturing and export are all in-house, we can respond flexibly to specification changes and OEM/ODM requests.
