Nakahara Daisuke’s (Okada Yoshinori) love for bentos (boxed lunches) developed into the opening of a bento shop. He has been too busy to go and eat ekiben (boxed meals sold at train stations and on trains) ever since. Then one day, his wife, Yuko (Kato Takako) gives him a rail trip around Japan as a present. He sets off on his trip and journeys with beautiful women (Yamamoto Hikaru, Haru, Sudo Atsuko) he meets while travelling as he consumes ekiben around the country including the famous ‘Fukushima Ajizukushi’, ‘Gyunikudomannaka’ and ‘Hanagasakokeshi’.
