It is absolutely true that Japan has some of the best parks on earth. The attention to detail, the aesthetics, the cleanliness are all unsurpassed, especially in this park. It’s one of the biggest and best in Japan. Unfortunately some of these same qualities work against the Japanese in the management of this park. The staff are so concerned about enforcing mundane, nonsensical rules that they ruin the experience of park goers who are just there to escape urban life and be in harmony with nature. The jumbo pool especially the lifeguards are the worst! They are like a military battalion, shouting at swimmers and to each other, running around in circles during their shifts, forcing people out of the water every half hour. You go down the big water slide and splash into the water and a lifeguard is there waiting to tell you to get out before you can catch your breath. Idiotic! The worst part is the office is run by a bunch of pencil pushing prefectural bureaucrats who could care less about customer service. They keep the park clean and tidy, but that is all they care about. Avoid any park that have staff in them. It’s a big park, so it’s doable. Enjoy!

As you see Japan is one of the safest and cleanest place in the world. The park is highly maintained and the atmosphere around it are so inviting. I'd love walking and talking photos as the garden arrangement were so nice. Have to come to see what i am talking.
