Ofuro Cafe Hareniwa Rugby Town Kumagaya

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.

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.

Events at Ofuro Cafe Bivouac spa resort in Rugby Town Kumagaya

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.

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.

Playing in the kids area of Cafe Bivouac Kumagaya Saitama Japan

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.

Tree house at cafe bivouac

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.

Chilling out in Cafe Bivouac Kumagaya Saitama Japan

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.
