Koishikawa Korakuen is a beautiful garden located in Tokyo's Bunkyo ward, and it's well-known as a spot for enjoying the best of autumn's changing leaves around the November timeframe. It's no slouch at other times of year, either, and the garden grounds are home to around 150 plum trees that signal spring's impending arrival – the blossoms are typically at their best during the February timeframe.
The Koishikawa Korakuen Plum Festival is held during this period, and along with the floral beauty there will also be cultural performances, guided garden tours, and food trucks selling various goodies.
Admission to the garden is priced at 300 JPY for adults, 150 JPY for seniors over 65, and free for elementary school-aged students and younger.
