Asue Ōsaka Pūru | Ａｓｕｅ大阪プール

I swam in the 50m pool. It was clean, well organized, and a comfortable temperature, although on the warm side, and relatively empty in the mid-morning. They seemed to be more lenient about the rules here than at other Japanese pools, as several people were using their own equipment and had water bottles on the pool deck.

Although it was a little outside the main tourist area, it was easy to reach by public transportation. Be aware that if you arrive by Metro, you have to walk out to the main road and go down the stairs to find the entrance.

Overall, it’s a nice place to swim laps.

When open, the 50 meter Olympic pool is a great facility, with a perfect temperature for serious swimming (between 27.5º and 28.5ºC). The lanes are not crowded at all, at least during daytime. Do not forget to check the schedule before coming, however, as some (or all) lanes might be used for clubs or events.

Take the Osaka metro to Asashiobashi station and follow the signs to “Osaka Pool”.

Clean with nice locker rooms, no extra charge for lockers, good hours 0900-2000, and right next to a subway station. The pool temp. was warmer than I'm used to; a sign said 30.1 - 30.3ºC, but I doubt it was that warm. The air, at ~30º, was too warm and humid. Osaka pool was better than most Japanese pools in this regard. Only the 25m pool was available. The larger pool is an ice rink in the winter and had not been converted back to a pool. Overall, I recommend this pool and will swim there again.
