We were staying not far from this vegan restaurant. It was a little hard to find but we were so happy when we did find it. None of my family could understand Japanese and it made being vegetarian in Japan difficult, so when we found this place, we were so happy. The owners are a husband and wife and we couldn't really understand each other but we did understand the word 'vegan' and nodded vigorously. They gave us each a set menu which was very well priced and very filling. The food was traditional style Japanese but completely vegan and very tasty.
They also loved our little one year old daughter, calling her cute and giving her cuddles.
The restaurant is tiny - maybe room for about 12 at full capacity. It's definitely worth it and if we ever return to Osaka, we'll be stopping in at Genmai Harmony.Pros: excellent food!, set menu, friendly staff
