In Wakayama Prefecture, there is a temple called Kimii-dera (紀三井寺), which was built in 770 D.C. Now a cable railway has been built because there are 231 stone steps in the approach for barrier-free.
There are 33 candle lanterns along the approach from the cable railway station, and each candle has a flame-shaped transparent shade created by Dasyn using the helical 3D printing method.
