Kotatsu boat

Information for the Kotatsu Boat Nagatoro in 2021. Its all happening in Nagatoro and Chichibu in January! Icicles, strawberry picking, wintersweet festival and a truly only in Japan activity of Kotatsu boat riding! From January 1st until Sunday February 28th you can ride a boat on the Arakawa in Japanese style: sitting under a warm Kotatsu.

On December 5th the organizers confirmed that they plan to go ahead with the event in January and February 2021 despite the coronavirus. Please do check with the official website for the most up-to-date information.

Kotatsu Boat

A kotatsu is a type of table you’ll find in almost every Japanese home. It is a low table with a removable top and a heater under the frame below the top. In Winter families put a kotatsu blanket between the frame and table top and turn on the heater for coziness to the max!

On the kotatsu boat they do the same thing. A blanket is placed between a frame of a long table and a removable table top. A heater below the frame keeps you warm as you sail down the Arakawa, Nagatoro’s most famous and beloved river.

In the area:

Mt Hodo is relatively close to the kotatsu boat ride. At the top of the mountain there is a wintersweet grove where there is a wintersweet festival during half of January and half of February. More information about the 2021 wintersweet festival in English here. You can also read about our experience of visiting the festival here.

For the last week of February and of the boat ride, there is a plum blossom festival on Mt Hodo. Information in English here.

There are three famous icicles of Chichibu that you can see during some of the period of the Kotatsu boat. The Otaki Ice Festival is the only naturally formed icicle display. In 2020 due to the warmer than normal winter, they never really did form and the event was cancelled early. But this winter looks to be a cold one, so hopefully they won’t have that problem. However, the pandemic may influence the situation. The other two icicles are Ashigakubo and Onouchi Hyakkei. It is best advised to travel by car to the icicles.

Last year several of the riverside attractions were closed due to damage sustained during typhoon Hagibis. For example, the two popular campsites – Waterpark Nagatoro and Autocamp Nagatoro. Thankfully both opened back up for business in 2020.
