A version of Honda's classic CB400 with a cowl. It is a long-selling model that has continued to be improved since its launch in 1992. This bike is a minor-changed version, with the newly designed NC42E engine replaced in 2007 by the NC23E engine, which has been used in Honda's sports models for more than 20 years. The CB400 is often used as a learner's bike, making it very easy for beginners to handle. The CB400 is so perfect that it is described as having "no faults" in the high school girls' motorbike life manga/anime Bak-ON.

The project was launched by Wanami Takahashi, a designer and illustrator from Fukushima Prefecture. The project mainly focuses on ramen restaurants in Fukushima Prefecture, but as of 2016 it has expanded outside Fukushima Prefecture to Miyagi and Yamagata prefectures, as well as Tokyo, and is active in a wide range of other areas.

A gentle but enigmatic priestess. She is a guardian deity who has been watching over the land and people of Koriyama since the Meiji era (1868-1912), when the Azeki Chosui waterway was first pioneered. She was weakened immediately after the earthquake, but she revived her body and soul after eating Shina-soba, a gentle and somewhat nostalgic dish from the olden days at Shozetsuya. When she eats 'kokkusan-soba', her personality changes.
