Heiwanomori Park

There's a fountain plaza with a carillon, a campground of 18 sites, a basketball court and a pool of its own.

A sandy beach recreating the old Omori shore, a 30-meter roller slide, and a museum next door on the seaweed farming the shore was once famous for.

Next to Shinagawa Aquarium, with a lake of seawater drawn in from the canal and an outdoor pool.

Kids ride loaner bikes and tricycles past real traffic signals here, and a junk park holds a steam locomotive, a Toden streetcar, trucks and boats.

A bakery in a renovated warehouse, baking bread from scratch all day, with deli sandwiches and cakes from its kitchen and a terrace on the canal.

A patrol car, a police motorcycle and the helicopter Harukaze up close, uniforms for kids to try on for photos on the bike, and free entry.
