Onoyama Park

Onoyama Park is known as the venue of many big events but it is also home to what I deem the funnest playground in Japan. As a mom of two kids aged 3 and 5, we have made the rounds of many many playgrounds but this is by far, the biggest and most fun playground we have ever been. We spent a solid two hours here testing out all the bridges, and slides, and climbing places. Best of all, it is free.
