Chichibu is the day trip I send people on when they've 'done' Tokyo and want mountains without a long haul. One direct Seibu train from Ikebukuro drops you in a valley town of carved shrines, river gorges and pink moss fields. It works as a relaxed full day - and if you time it to a season, it's one of the best near the city.
Take the reserved-seat Laview 'Red Arrow' limited express from Ikebukuro - comfy, scenic and direct.
Start at the ornately carved shrine, then wander the low-rise old streets - sake shops, a morning market on some days, and miso-pork lunch spots.
Ride a traditional flat-bottomed boat through the rapids, then walk the flat 'iwadatami' rock shelves along the river.
In spring, bus to Hitsujiyama Park for the shibazakura. Otherwise, end with a tasting at a town-centre sake brewery.
Yes - it's a direct 80-100 minute Seibu train from Ikebukuro to a mountain valley of carved shrines, the Nagatoro river gorge, sake breweries and big seasonal events like the spring shibazakura and December night festival. It's a proper countryside change of pace.
A full day suits it - the shrine and old town, a Nagatoro gorge boat ride, and a seasonal highlight or sake tasting. You can also stay overnight to catch the December festival or winter ice displays.
