The indoor pool is on the older side, built in the 70s maybe. It has weird rules about swimming – the three lanes for lap swimming are divided into two lanes, each about 1.5 lanes wide, you go down one lane (it’s ok to pass), duck under the lane line, and swim back the other way… There are hourly ten-minute breaks when everyone has to get out of the water. The usual Japanese public pool rules about no tattoos (if you have one, you have to wear a rash-guard or large bandage or leggings), and no wristwatches or jewelry is allowed in the pool.
