The private hot spring booked on the same day has a half-hour time limit plus ten minutes to sort out. The clothes are also outdoors but there are half walls separated, and there are no people in the lake. In fact, you don't have to be shy. But the place to take a shower is on the hot spring side. It is outside the wall. There will be a press-type direct drinking water next to it. I went to the hot spring for two consecutive days. Hahaha. I took pictures while soaking. There are many hotels next to this hot spring. I live very close to Millennium.
