Tokyo Tower

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.

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

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

On the 38th to 43rd floors, with living walls of plants and a family package with an in-room kids' tent and wooden toys.

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.

Locals call it Robo Robo Park for its colorful robot tower inspired by tin toys, at the south end of Roppongi Hills.
