Mt Hodo is a mountain in the Nagatoro area of Chichibu, Saitama Prefecture. At the top of the mountain there is a plum blossom grove. There are close to 500 plum blossoms in the plum blossom grove on Mt Hodo. Every year, while the plum blossoms are in bloom, the Nagatoro Tourism Association hosts a plum blossom festival at the garden. They set the dates close to the time of the festival after watching the weather conditions and the patterns of bloom of other flora on the mountain.
Generally, the festival is held from around February 22nd to mid-March. The first weekend of the festival usually overlaps with the last weekend of the wintersweet festival that is held in the neighboring wintersweet garden on the mountain. During the period of the festival they host several special events including hiking and food events.
