Tokyo Summerland 1Day Pass

This water park has both indoor and outdoor areas. The indoor area, like a greenhouse, can be quite humid. On the left, you'll find an inflation station (4 stations) for large inner tubes. The outdoor area features a huge lazy river and a kids' play area. There are two large water slide attractions (Tower's Rock and Dekasla) that require a separate pass, which often sells out quickly. Monster Stream is a wild and wavy lazy river, a free attraction where you queue on-site. It goes around twice and is well worth experiencing!

Booking through Klook was super easy and convenient — we got instant confirmation and just scanned the mobile voucher at the entrance. No hassle at all! Tokyo Summerland itself was fantastic. The water park had so many attractions for both kids and adults — from relaxing pools and lazy rivers to exciting slides that kept us entertained the whole day. My kids especially loved the wave pool, and we appreciated the clean facilities, plenty of seating areas, and friendly staff. The park is very family-friendly, and even though it was busy, everything was well organized. We also enjoyed the outdoor rides and attractions — it really felt like two parks in one! Overall, this pass was such a great value. If you’re visiting Tokyo in the summer, I highly recommend spending a day here. We’ll definitely book again through Klook!

A big thank you to almost all of the team members—most of the staff were friendly, helpful, and very cooperative throughout our time there. However, we had a very disappointing experience with the staff operating the Star Wheel, as they were uncooperative and treated us poorly. Queue Times: There were noticeable delays in the lines even though the crowd and visitor numbers were quite low. Transportation: The shuttle buses connecting the park to the metro station were heavily delayed, which forced us to take expensive taxis instead.

The water park has both indoor and outdoor areas, and it's a lot of fun! The kids didn't want to leave.

It's quite a distance from Tokyo, and it's crowded even on weekdays during summer vacation. The wait for Dekasla is an outrageous two hours, but the actual ride lasts less than a minute. I recommend eating lunch while waiting in line. Monster Stream is great fun and worth the 30-minute wait. There are many types of food and drinks available in the park at reasonable prices.

kids 4 and 6 had an awesome time they enjoyed the pools and the food options were pretty good too . the amusement park and large pool was closed though so that was a shame. kids enjoyed the free zoo train ride I enjoyed the crazy waves and sudden disco party in the pool every hour! all in all a pretty awesome experience

super quick and easy to enter, all you do is scan your QR code on the Klook app at the entrance. You can rent a spot with tables and chair for around 5,000 yen + 1,000 yen cash deposit and parking is 1,500 yen! Be sure to bring Yen. we had a good time and easily spend a couple hours here. If you do not want to pay for seating be sure to bring a mat to sit on to claim your spot for the day

I was able to use it very cheaply for a limited time until June. It was hot like summer, and I enjoyed the outdoor pool which was almost fully open! The price will be higher from July, so I won't be able to go frequently, but I would like to go again if there are any good coupons!

At the wave pool, they allow floaties. It gets too crowded and dangerous. You could easily get swept under and get stuck. The waves only run 1x/hour, for 3 minutes. Bummer. The lazy river is nice. You can only sit on the ground unless you pay for a table. Took 40 minutes at closing time to leave the parking lot. Absolutely no tattoos, not even covered ones, are allowed. The lazy river was worth it, and we'll be back.

Today was a lot of fun! It might have been a little chilly, which meant it wasn't too crowded, and the Samarang Wave event was also happening. We had an entry code in advance, so we were able to get in smoothly, which was very satisfying.
