Asu Sports Park in Hanno City is just across the road from the very unique Akebono Children’s Forest. It has a nice playground for younger kids as well as a spider web climbing frame for all ages. The area around the spider web climbing equipment and the toddler play equipment is a giant sandpit.

Asu Sports Park Access
BY CAR
Approximately 20 minutes from both the Sayama-Hidaka and Iruma Interchanges of the Chuo expressway. The park is situated across from Hanno’s city public gym and hockey courts and the Akebono Children’s Forest. There is a Cainz across the road too, which is probably the best landmark. They are on prefectural route 195; 9 kilometres from route 16 if you come of the Chuo Expressway at the Iruma Interchange.
BY TRAIN
A 20 minute walk from Motokaji 元加治 Station on the Seibu Ikebukuro line.
Z would love a playground like this! 🙂 Looks fun!
