Because Yufu city has a strong image of Yufuin hot springs(Yufuin Onsen), many people think that our factory is located in the mountains in the countryside very much.
However, adjacent to Oita city, the prefecture's capital city, various delivery services are treated almost like Oita city.
In addition, Yufuin and Beppu hot springs(Onsen) can be reached by car or train in about 30 minutes.

Access Please confirm from the common page for details.
* Our head office factory is about 10 minutes by car.
