Sotetsu Fresa Inn Tokyo Roppongi

The bright robot towers and long slides make this tiny park feel like a piece of public art kids can climb on.

A calmer central-Tokyo base with apartment-style rooms that work much better for families than a standard tiny hotel room.

Rooms of moving light and digital art flow into each other, so kids can wander without feeling like they are in a normal museum.

A high-end option that explicitly accommodates children in several room types and has a pool with child swimming hours for ages four and up.

Arcade style games, simulators and digital sports make this a strong rainy day choice for older kids and teens.

Older kids get a kick out of the glass floor panels, and the compact main deck is easy to do without committing half a day.
