I first met Ocha Inu when I got thirsty one day in Sapporo. I went to the bookstore on Hokkaido University's campus and bought myself a cold bottle of green tea.
Attached to the cap was a bag. I tore open the bag and out fell a small green dog on a keychain! My Ocha Inu [Green tea dog] obsessions was born... Now there are Ocha Nekos [Cats]!
