Nagatoro Valley Complete Travel Guide

Nagatoro Valley is a scenic stretch of the Arakawa River in Chichibu, Saitama, known for traditional wooden boat rides past flat rock terraces called Iwadatami, and it works well as a nature-focused day trip roughly 90 minutes from Tokyo.

Quick Facts

Best Things to Do

• Take a traditional wooden boat ride through the Arakawa River rapids past the Iwadatami rock terraces.
• Walk the flat, free Iwadatami rock formations along the riverbank.
• Check the seasonal Chichibu Railway SL Paleo Express steam train schedule if a nostalgic train ride fits your visit.
• Combine with Hodosan Shrine and its ropeway for valley views, when the ropeway is in seasonal operation.

Tickets and Fees

Checked in July 2026: viewing Iwadatami is free. The traditional boat ride is paid and priced by course, roughly yen 2,000 to 3,500 for adults depending on route and season; boats generally run March through December and are weather dependent, so book ahead for weekends and check for cancellations on rainy or low-water days.

How to Get There

From Ikebukuro, take the Seibu Limited Express to Seibu-Chichibu Station, then transfer to the Chichibu Railway local line to Nagatoro Station, about 90 minutes total. The Iwadatami rocks and boat piers are a short walk from Nagatoro Station.

Nearby Attractions

Nagatoro sits on the same Chichibu Railway line as Chichibu Shrine, so the two are easy to combine in one day.
