As a way to promote ridership, the Seibu rail company has produced detailed topographical hiking maps for the Chichibu area of Saitama Prefecture: https://www.seiburailway.jp/railways/hiking/index.html

For the non-Japanese readers, I’ve posted links to all of the maps.  Each map in the table below is numbered, which corresponds to the following Google map (click to open).

The closest hikes are just 45 minutes from Ikebukuro Station.  For example, see a review of Map 9, Tokyo hiking: Murayama Mountain 丸山 , Ashigakubo Station 芦ヶ久保駅.
