Misotsuchi icicles lit up at night, aka Otaki Ice Festival Ogano

The Otaki Ice festival, illuminated Misotsuchi Icicles in 2024 will close earlier than initially planned. It was only announced on February 11th that they will close on the 14th. They don’t give a reason, but it has been a very mild winter, so I would speculate it is because the condition of the icicles isn’t good enough.

One of the most famous, and beautiful, winter scenes of Saitama is at the Otaki Ice Festival. Located in the former Otaki village (now part of Chichibu city) in the Chichibu-Tama-Kai National Park. The Misotsuchi Icicles are the only naturally formed icicles of the three Great icicles of Chichibu.  They light the icicles of Misotsuchi up at night. Each year for about a month you can enjoy this spectacular view in Chichibu, the mountainous area of Western Saitama.

The Otaki Ice Festival was one of only a few January events that went ahead in 2021 despite the pandemic and a State of Emergency. They opened in 2022 too, when few other places did and it was actually one of the best years for the icicles to date thanks to suitable climatic conditions. Between 2019 and 2021 unsuitable weather patterns significantly impacted the formation of the icicles and shortened the period of the festival. Hopefully 2024 will be another cold year that keeps the icicles in prime condition for as long as possible! Update February 11th 2024: the icicles will be close on February 14th, 11 days earlier than initially planned. This year they were also later to open than scheduled, due to the warmer than normal winter.

Misotsuchi Icicles

Misotsuchi Icicles

The Misotsuchi icicles form completely naturally. The main display are neither altered nor aided by human hands. The icicles form from spring water bubbling from the rocks aided by the winter environment of the Okuchichibu region. The icicles are ten meters tall and thirty meters wide! They look spectacular when lit up at night, particularly with the lights reflected in the water. They use four different colors to represent the four seasons of Chichibu-Tama-Kai National Park.

You can view the icicles from either the North side or South side of the Arakawa (Ara River). On the North side, which is more popular because of the convenience, the entrance is by the Woodroof campsite. Moreover, the icicles can be seen from the car park of Woodroof campsite for anyone who is unable to take the craggy, icy walk down to the riverside.

On the south side the entrance (and parking) is at the Tsuchiuchi Camping grounds. It is further and harder to get to. However, Tsuchiuchi campsite have even more icicles – man-made, but equally impressive. They are 25 meters high and 55 meters wide. (You can see them from Woodroof too). Also, Tsuchiuchi serve hot food and drinks during the period of the Otaki ice festival. Please note that neither campsite take over night guests at that time of the year (season is from April to October). 

In 2020 the icicles were late forming due to the milder weather. They never really formed properly so there was no entry fee. And for the same reasons they did not support the icicles during the week and only opened the icicles to visitors on the weekends. However, the weather conditions were initially better in 2021. But the milder than normal winter melted the icicles much earlier than normal. Thus, the event abruptly ended earlier than expected. In both 2022 and 2023, they actually extended the period of the ice festival due to the suitable climatic conditions. Summer of 2023 was much longer and hotter than average, we will have to wait and see how winter fares!

The entrance fee went up in 2023. From 200 yen to 400 yen for adults or high school aged children. HOWEVER, currently the website is showing the price as 200 yen in 2024. I don’t know if that is an error on the website or if they have reduced the price in 2024. There is no charge for younger children.
