Onna Hitori Nihon wo Yukkuri nonde Mita yo

A 40-something manga artist, a complete homebody, travels around Japan visiting friends and acquaintances while enjoying drinks and food. She wanders through entertainment districts, pops into any place that catches her eye, and sometimes sightsees just to work up an appetite. It's a carefree trip where she goes wherever her heart takes her, with no plans other than drinking! She introduces eight prefectures: Kagoshima, Himeji, Akita, Yokohama, Matsuyama, Mito, Fukui, and Wakayama, plus a little bit of her hometown, Hiroshima.
