This sturdy, foldable map covers the railway coverage of some of Japan's largest cities: Tokyo, Osaka, Nagoya, Fukuoka, Sapporo, Sendai, Kamakura, and Hiroshima. The map is incredibly detailed, as Hobonichi revises it every year with the help of crowd-sourced checks by Hobonichi readers. The writing is all in Japanese, but the train maps are also popular as posters. The A6 and A5 size maps fit into the pockets of their respective covers, A6 Planner / Original and the A5 Cousin.
