Hotel Gajoen Tokyo
If you love art, then this hotel should be your lodestar, as everything—from the ornate entryway and the koi pond to the chapel (the property was a wedding complex in the 1920s) and the Chinese restaurant—features elements seemingly plucked from a renowned art museum. Tours are even available to appreciate the hotel's gestalt. The grounds are tranquil thanks to a leafy location close to the Meguro River, one of the city's prime cherry blossom viewing sites. When you've finished sightseeing for the day, head to the eight-floor OUKA lounge for tea or cocktails and some light bites.
