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 "rest area" as a (possibly not very comfortable) 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, better 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!

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.
