Next stop: Water play until the 16:00 closing at a water-recreation facility with a waterfall and pondAbout this spot
A station building directly connected to JR Omori Station (大森駅), with restaurants and a food floor. Since you can enter from the station without getting wet, it is reassuring to know you can have lunch without changing plans even if the weather turns. Many restaurants offer children's menus, so the lineup is easy for families to use. You can also buy a bento on the food floor and eat it in the park. Iriarai Park is within walking distance, so you can head straight to the water play after eating.
Tips
Restaurants get crowded at midday, so arriving a little early cuts the wait. Please check business hours and closed days on the facility's official page. The layout is easy to navigate with a stroller, but it is busy on weekends and holidays, so checking elevator locations first keeps things smooth. On days when you are carrying a lot of water-play gear, locating the coin lockers lets you move around unencumbered.
Best time to visit
About 1 hour. Shifting slightly off the lunch peak makes for a relaxed meal
