Sakurazaka Park

The big Roppongi Hills hotel, with an indoor pool, and the Mori Tower, the cinema and a dozen places to eat right outside the door.

Connecting twin rooms, pajamas to wear in-room, and a simple buffet breakfast from the café next door, right at the main crossing.

Hills, a stream and a pond, with a sandbox, spring riders and a wooden play structure, and the metropolitan central library inside the park.

A kids-only bakery where children go in on their own, pick their own baked treats and get their change back.

Two Japanese-style rooms joined by a door, each with its own bathroom, sleep eight adults and four kids, and high-floor rooms look over the city.

Artworks that wander out of their rooms and into each other, and a Sketch Ocean where the fish kids color swim off into the sea.
