19. Keio Plaza Hotel, Tokyo
At first glance, the Keio Plaza Hotel doesn’t look like it should be on this list, but hidden beneath the classy 4-star hotel sheen is a collection of Hello Kitty-themed rooms, which feature an extravaganza of Hello Kitty paraphernalia. Fans of the kitsch anime cat will love it. There’s also a rooftop pool on the 7th floor and a karaoke parlour on the 47th floor. And because the hotel is so tall, there are some fabulous views across the city from most of the rooms.
