The 50-meter main pool (Pool 1) is usually closed to the public as it is used for regional and other swim competitions and groups. The schedule shows that the sub-pool (Pool 2) is the one that is open most frequently. I found that the water in the sub-pool felt cooler than most community pools in Tokyo, which are more in the 83º - 85ºF (28º - 29ºC) range. You can do flip turns on either end and circle swimming is the norm with people being very conscious to give way to faster swimmers. No watches, jewelry or tattoos are permitted!
The facility is a bit out of the way in Yokohama but easily accessible by public transport. You have to climb a steep hill / flight of stairs to get up to the facility. You purchase your ticket from a vending machine and use it to get in. Keep the ticket as it is used to secure your locker, and you need it to get out of the facility. The locker rooms are antiquated compared to the Tokyo Metropolitan Gymnasium and the Tokyo Aquatics Centre even though the facility is newer than the Tokyo Metropolitan Gymnasium, which was first opened in the mid-1960s.
