Nippori Minami Park

A broad artificial-grass slope kids sled down, a pond area for water play, several playgrounds and about 1,000 cherry trees.

Kids ride a free slope car up the hill to a playground, a retired D51 steam locomotive and an old Tokyo streetcar, with three museums close by, one all about paper.

A pond you can fish in, a big windmill, a splash pool for kids, play areas and a bird sanctuary.

Japan's oldest museum, founded in 1872, with samurai swords and armor and a garden with five traditional teahouses.

Tatami rooms with futons that sleep five, up to a Park Side Suite that sleeps six, every apartment with its own kitchen and washer-dryer.

Penguins in a rooftop garden that look like they're flying over the city, plus great white pelicans and sea lion shows.
