Ninja Park — Local services in Tokyo

Unreasonable pricing for accompany parent - you will have to pay for the same amount of money as your 5 yo child just to take care of them and be inside the so-called "park" but really just a 200square meters area in a mall. It's not like a parent is gonna jump on that trampoline or anything, the pricing just doesn't make any sense.

Plus, if you are a first time user accompanying your child, both you and your child will need to register as a member, and pay 500 yen each for their membership cards.

If you are going on a weekend, here's how much you'll have to pay for 90 minutes if your child is less than 7yo: 5600 Yen = (2300 rate + 500 registration fee) * 2 for you and your child.

Some may argue that if your child is above 7 (eligible for elementary school) you won't have to accompany so the cost will be in half, but the facilities inside I really doubt will interest any kids that big.

In short, if you really just wanna spend 5600 yen for 10 minutes with your kids there until they get bored,...

The great time we had was all ruined by the very unfair charge that we were forced to pay when we left the ninja park. Without being pre warned, we did not know we had to report at the desk when finished, and we had even spent our time getting our shoes at the desk, drinking water, cutting off our bracelets, to then be pointed out that we were 7 minutes overtime. Even though we had finished at the park on time. We were charged ¥1,500 for this. I disagreed with the staff, who was enforcing the payment, he then proceeded to say that he would call the police if I don't pay....

The place is average. It is a set of trampoline, jumping areas, basic gym for kids. It lacks diversity and it is pretty basic. It is a good option if you are in the mall for other reasons. I would personally not come back just for that. Plenty of other options to get kids...
