Tokyo Skytree

The plates are ridiculously cute and much better executed than most character cafes, but getting a reservation is the hard part.

Compact enough for little kids, with a big penguin pool and jellyfish displays you can pair with the tower upstairs.

The salt exhibits are surprisingly hands on, and the low admission makes this an easy add on rather than a whole day.

Earthquake, storm and smoke simulations make this free center much more exciting than the phrase safety museum suggests.

Separate sleeping areas and a kitchen make this feel much closer to a small apartment than a typical hotel room.

The roomy apartment setup is the draw here, especially if naps, snacks and early bedtimes are still part of your day.
