Updated in summer 2015: The playground at Tokinosumika has undergone some changes and is no longer free for everyone, but they have added lots of attractions including bouncing castles and other equipment.
The playground remains free for children under 7. It costs 800 yen for adults and 500 yen for children 7 and over, but guests of the resort get a half price discount. You can come and go as you please all day for that price. At night part of the playground is used for the water, illumination and projection mapping show to music. Guests of the hotel also receive a half price discount for this show. Children under 7 are free for this attraction too.
There is something for everyone in the “Big Bang” playground. They have an area for smaller children which is on sand. It has slides and climbing and some spring rides. There is a choice of bouncy castles for older children, which have slides in them as well as other features. There is a giant inflated slide for over fives and it is quite steep and fast making it one of the most popular attractions. My favourite is the merry-go-round, pictured with Mt Fuji above. The featured photo at the top of this article is of the obstacle course, which is also inflated like the bouncy castles. There are see saws and wooden equipment too, including stepping stones, and in the summer there is a splash pool. There is an inflated jumping mountain for over threes. They also have events in the area some weekends and over Golden Week. A bonus is there is an amazing view of Mt Fuji (on a clear day) from all of the playground. (A lot of the equipment is pictured in the gallery below).
