Lovely park. Few things inside you can do for a little extra but some of those things could be better maintained (specially with the entrance fee being 900 yen for an adult and the extra activities ranging from 100~300 yen per person) entrance fee includes the waterpark section and petting zoo [which are currently closed due to covid] and the various play parks dotted all over the park - great for kids, but perhaps reduce the ticket price when half of the stuff is closed due to covid??? Kids do get in cheaper though (depends on age, with under 4years being free and scaling up from there... sort of between 100~600yen ish - see their website for up to date pricing. You can buy advanced tickets which are about 100 yen cheaper per ticket on average 900->810 etc).

Golf putting was fun and quick activity for only 100yen per person but the 9 holes were a little bumpy with only bare minimum maintenance very evident. (I didn't expect much, but you can tell it's not particularly thought about for maintenance when they're deciding where to spend money). The "funny bike" course is VERY short but for only 200yen for a 1~2 person bike and 300 yen for the 3~4 person bike it's pretty reasonable for a bit of fun. Overall it's a nice park. Worth visiting at least once, specially if you've got kids. You can easily spend the day here if you wish to. Entry price is a bit steep (specially with so much being closed that would normally make it ok) and those extra 100~300 yen activity costs per can add up if you have a big family.
