The "Candle Night"​ is held at the Matsumoto City Museum of Art every year around the summer and winter solstice to enlighten people on environmental issues. It is a nice (and free of charge!) event to enjoy a fantastic night by only the light of candles on green glass in the yard of the museum with art and live music.

Matsumoto is popular with its oldest castle in Japan and surroundings of beautiful nature, but also it is a town of a modern culture of music, art, and crafts.

The famous modern artist Yayoi Kusama is from Matsumoto and you can see her many works in this art museum.

At one of the previous candle night events, a big objet d'art, "The Visionary Flowers", was lit up by candles as well, creating a more mysterious​ than usual Candle Night.
