Toneri Park

The train theme is the fun part here, with play equipment for preschoolers who love vehicles.

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.

Rows of poplars and a metasequoia grove along a reservoir, with a bird sanctuary for birdwatching and about 14,000 irises.

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.
