Yomiuri Land's summer-only outdoor pool area is opening again, so get ready to enjoy a total of five pools, several water slides and lots of fun events – how about chilling in the predictably tame Anpanman pool before heading over to the curvy slides and the 'wave pool'? Adults will also enjoy the night-time beer garden that's spread out on one of the nearby lawns.
Pool entrance ¥3,200, high school and junior high students ¥2,500, younger children ¥2,100. One-day pass (includes unlimited rides at the theme park and pool entrance) ¥6,000/¥4,800/¥4,400. Opening hours vary by the day – see this calendar on the official website for full details.
