Oga Drugstore Tenjin Underground Mall Store is a drugstore in the Tenjin Station underground mall that sells medicines and cosmetics together. Ointments, Canmake cosmetics, toothpaste, and mouth ulcer cream are all available in one place. A Korean-speaking staff member is on site, so products can be asked about in Korean, and tax-free shopping is available. Snack items are limited, so Don Quijote is the place to go for those.
