Ueno Park

It's a mystery why so many guidebooks implore tourists to visit Ueno Park during their stay in Tokyo. The sprawling site enjoys historical significance – it was one of the capital's first official parks, established way back in 1873 – but you'll find more attractive spots of urban greenery elsewhere. That said, it is worth visiting for the museums that are housed within the park (including the National Museum of Nature and Science, and Tokyo National Museum) and for Ueno Zoo, Japan's oldest.
