Kokoen Lantern - Ishidoro lanterns are usually used to decorate Japanese gardens, shrines and temples rather than for providing light, although occasionally they are lit up with candles inside during festivals. Ishidoro Lanterns were introduced to Japan via China in the 6th century. The earliest lanterns, found only in temple grounds, were designed to hold the flame representing Buddha. Light helps us overcome the darkness of ignorance. Ishidoro were originally used at temples, gardens and shrines. Around the 16th century stone lanterns were adopted and placed in the gardens of teahouses.
