Mt. Horaiji is known as a top place to enjoy splendid autumn leaves from mid to late November. Looking upstream from the promenade on the banks of the Tomoe River, over 4,000 trees are bathed in autumn colors and reflected in the clear waters of the river below. In this season as the Mt. Horaiji Maple Festival takes place, all manner of events are staged and local specialties are sold. November 23 is the main day of the festival and if you can make it then, there are loads of things to do even besides the autumn leaves.
