If you’ve always thought Nagatoro was just about adrenaline-pumping white-water rafting, think again. Winter transforms this popular getaway in Saitama Prefecture into something wonderfully slow and cozy. From January through February, visitors can hop aboard kotatsu boats to enjoy peaceful river views while staying toasty warm under a traditional Japanese heated table.
Why Winter Is Perfect for Kotatsu Boat Cruises

Unlike the fast-moving river rides of summer, the Arakawa River’s water level drops in winter, creating long, calm stretches known locally as toroba. These gentle currents make the perfect setting for a slow-paced kotatsu cruise, allowing passengers to relax and take in the scenery at an unhurried pace.
Iwadatami Rocks: A Scenic Winter Highlight

Seated around a warm kotatsu, passengers can admire the dramatic Iwadatami rock formations rising along the riverbank. Formed millions of years ago by geological uplift, these striking rocks are designated both a National Place of Scenic Beauty and a Natural Monument, offering a rare chance to enjoy one of Nagatoro’s most famous sights in peaceful winter surroundings.
Locals and visitors alike say the kotatsu boat experience is more than simple sightseeing. It’s a chance to slow down, soak in the quiet winter landscape, and feel both physically and emotionally warmed as the boat glides gently downstream.

Kotatsu boat cruises typically last around 20 minutes and operate throughout the winter months when weather and water conditions allow. For travelers looking to experience a calmer, cozier side of Nagatoro, this unique winter activity makes for a memorable—and wonderfully warm—detour.
Discover Nagatoro Beyond the River

Beyond the river, visitors can explore seasonal flowers, scenic hiking trails, and historic landmarks such as Hodosan Shrine. The area around Nagatoro Station is lined with restaurants and souvenir shops, making it an ideal place for a relaxed stroll before or after a river cruise.
