50m - #45 Fukushima Moriai Shimin Pool

This was also great and nice pool.  Not made for competition but still a good one.  Only two lanes are reserved for lap swimming so if there are few more serious swimmers, it might get a bit crowded.

50m - #44 Fukushima Chuo Shimin Pool

Great pool.  I was the only one swimming in this pool until some kids joined me after 30+ min.  Clean and nice facility.  Well maintained.  The only issue I had was that I was forced to take 5 min break after 25 min of swimming.  Cannot swim long distance with only 25min.

50m - #43 Utsunomiya Yonan Pool

The pool was even older than Eki-higashi pool.  However the water was clean and three lanes were kept for lap swim.  I was the only one in the lane.  The surface gets super hot so it would be better to bring your sandals inside.

50m - #42 Utsunomiya Eki-higashi Koen Pool

Nice pool with clean water.  Many lifeguards.  Lockers are small with 100yen coming back when you are done.  Facility is pretty old and not many people are using the pool.

50m - #41 ToBiO, Hamamatsu

One of the best swimming complex in Hamamatsu Japan.

50m - #40 Sagamihara Green Pool, Kanagawa

Great pool for competition.  But far from the station.

50m - #39 Nohoro General Gymnasium Park Swimming Pool

Excellent 50 pool in Nohoro.  The facility was used for the National Athletic Meet in 1989.
