if we are just going to use the public pool for a few hours do i need to make reservation? What do I need to bring to the hot spring?
Yes anyway you have to make the reservation, otherwise even the public bath it could be not available.
And I'm not 100% if reservation is compulsory coz before entering their main entrance, they need to check your name on the reservation list.
