Ooedoonsenmonogatari Urayasu Mangekyo, Urayasu

Great Japanese-style spa, including indoor and outdoor hot baths, steam bath and sauna. Open 24 hours, so it's possible to use the tatami-covered "rest area" as a place to spend the night in for just ¥900 extra charge. Also beware the complimentary lockers are really small, so if you have, say, an airline-size in-cabin bag, you will need to pay at least ¥200, not refundable, to rent a bigger locker. In-house restaurants, one of which with meal ticket machine. As of December 2022, face masks are compulsory in the dry areas, and compliance is enforced. Also strictly no tattoos policy, and it doesn't say anywhere you can just cover them up with a bandage, so if you have any tattoos, stay out. Credit cards accepted, but it is a good idea to bring enough cash anyway, because payment is when leaving, and if one doesn't settle the bill, they won't let you out!

I love this onsen! I particularly enjoy the sauna and cold soak alternately. The baths are all well kept. The natural spring water bath indoors is my favorite. There is no waiting time for the shower and the dressing area since there are lots of it even on weekends and holidays. There are numerous dishes to try at the restaurants as well as snacks when you fancy taking a break from the baths.

Wonderful place! Plenty of onsens, clean and tidy. There are affordable restaurants inside. You can rent towels and robes. They have shampoos and conditioners but I suggest you bring your own as they are not very good. Worth spending a whole day there. Keep in mind if you have tattoos you need to purchase stickers which are ¥220 each. Can get very expensive if you have many tattoos. They are strict about that

We didn’t have the chance to explore the whole place. But the overall experience was great! The game corner had a lot of machines that didn’t work anymore, and due to a recent fire, two restaurants were also out of commission. It felt like the general space could use a bit of renovation but again, the overal experience was great.

The outside baths were okay, it was nice to enjoy a bath with opposite gender. The swimsuit rental sizes run really small for females from the US. My friend usually wears size small in the US and Large was very uncomfortable for her.
