Ofuro Cafe Hareniwa no Yu in Kumagaya, Saitama Prefecture, Japan. (Formerly called Bivouac)
2019 was the first year that Saitama prefecture was represented in the prestigious All Japan ofuro competition Ofuro Koshien . Not just one, but two of Saitama’s hot springs were selected: Retro Onsen Tamagawa and Ofuro Cafe Bivouac Hareniwa no Yu. Both owned and managed by Onsen Dojo. Both placed in the competition, as runners up. If you’ve ever been to either you’ll know why.
Ofuro Cafe Bivouac Hareniwa no Yu

Cafe Bivouac Hareniwa no Yu is certainly one to bookmark if you are in or coming to Kumagaya for the Rugby World Cup, but please note that, regrettably, they do not allow anyone in with visible tattoos. If you have tattoos that can be covered up with clothes you can use the many facilities, but unfortunately you cannot use the baths.

The water used in the baths in Hareniwa is not natural to the area, but is shipped in. But what makes this hot spring resort special is more than just the baths. The complex is a leisure resort with a multitude of offerings for a full day’s worth of pampering and play. You can even stay overnight cheaply in their capsule hotel style sleeping booths.
Hareniwa System
When you enter the building you take off your shoes and put them in a lockable shoe box. Take the key to the reception area where they will mind it for you until you check out. You get a band for your wrist with a readable bar code. You use this for any purchases within the resort, including vending machines. This will be added to your bill and you pay on your way out.

Children’s Play Area
Initially, when Cafe Bivouac opened its doors in 2016, it was for adults only. In 2017, just a year after opening it underwent a renewal and reopened as family friendly with several things for children to enjoy, included in the entry price.

The popular kids play area is great for kids under eight years old. It has a ball pool, climbing wall, tree house, tee-pees and children’s books.
Bouldering

On the first floor there is a large bouldering wall for adults and older children. It costs 1000 yen for an hour and 200 yen to borrow climbing shoes.
Cafes and Restaurants

On the first floor there is a small cafe selling fast food such as hot dogs. There is also a bar. On the upper floor there is a larger restaurant with fantastic decor. The latter has a kids plate on its menu. There is a cafe beside the restaurant too.
Events

The spa has events almost every day. They vary greatly with larger events for big seasonal occasions such as Halloween and Christmas. Yesterday was the first time any of my family actually participated in an event. Normally we just use the various facilities.

Yesterday’s event was a big bingo competition to celebrate the three year anniversary of the resort. The prices, 130 of them in total, were amazing including large prizes such as tickets to Disney, a Nintendo Switch, a Twin Bird’s bread maker and an air purifier. With well over 130 people participating there wasn’t a prize for everyone, but they had a consolation prize for those who weren’t among the lucky 130.
Upcoming event winter 2025 – Shishimai Performances
For New Year 2025 there will be a shishimai parade in the hot springs daily between January 1st and 3rd from 3 pm. There is no additional charge. Between the 1st and the 5th they have a festival game area for kids. It costs 500 yen for five tickets which can be used on games of your choice. Fukkachan, the popular mascot of Fukaya city, will visit the hot springs on the 4th and 5th and play rock, paper, scissors with the kids.
They usually have an event for Setsubun too. Setsubun is on February 3rd annually. In 2024 they had a bean throwing event at not just on February 3rd, but two dates in January too. Information for 2025 not yet available.

Impressions
My family of six really love this spa resort. It is quite far from us so we don’t go that often, but when we do there is something for everyone. It is a great location for a rainy day or a very hot day.

My younger two, aged four and six, really love the play area. We usually just use a two hour package if we are not entering the baths and they spend the whole two hours in the play area. The youngest, would easily spend longer there.

My older two, currently aged ten and eight, recently find regular play centers and playgrounds boring. They enjoy hot springs though and the manga and climbing at Hareniwa. There is a work station area with computers they can use freely. They also enjoy the hammocks and tree houses. They loved the bingo competition yesterday and were very fortunate to be among the prize winners.

Personally, I love the variation of the baths and the sauna, as well as the chill out pods, hammocks and generally the glamping decor. It is one of a few places of its type that I am happy to visit over and over again. And it really does offer relaxation and chill out time. For me, it is definitely on the “best of Saitama” list and its award as one of the best spas in all of Japan is definitely well deserved.
