Maples and zelkova are colored from late October to mid-November in the Asahi-nakoka Lakeside Green Park on the southern shore of Lake Yamanaka, and light-ups are performed at night. This lakeside has been chosen by Japan's Nagisa Hyakuseki as the "Lake Yamanaka Sunset Nagisa", and during this period, the autumn leaves add to the beauty of the lake surface of Mount Fuji and Lake Yamanaka, which is reflected in the evening and sunset, so you can enjoy the scenery like no other. In particular, it is a limited time period when Fuji, which is the silhouette after sunset, and the illuminated autumn leaves are seen. Since the elevation is close to 1000m, it suddenly becomes cold when the sun drops, so take measures to protect the cold for walking after the evening.

It is known as "Yamanaka Myojin Ansei Festival". The main priest is Toyoda Hime. After departing from Suwa Shrine at 18:30 on the 4th Evening Festival, Kamikoshi is laid down overnight in an inn that becomes a makeshift inn in Kamikoshi, about 1km away, and is filled with thanks and 100-member pregnant women and ladies. In addition, the 5th Main Festival is an unusual festival where pregnant women with large tummies, mothers with children on their backs, and women who wish to be blessed with children are connected to Shinkoshi.

The top batter of the fireworks display held at each of the five lakes of Fuji every summer is the Lake Bai, which is held at Lake Yamanaka. It began in the Taisho era as a remembrance, a hoisting firework of evil, "respecting the martyrs, comforting the spirits, and offering thanks and prayers to the grace of the lake so that there is no calamity." the details are required by the official website.
