Along the main streams are girls selling candles that float on delicate flower-shaped styrofoam boats. Tourists can purchase one, make a wish, and send their candle down the waterways. Late in the evening after groups have had significant amounts of alcohol you can see many floating candles sailing down the waterways. If you are environmentally conscious and have reservations about sending styrofoam downstream do not worry. There is a net, far down the waterway, that catches the boats. The girls just go down, pick the boats up, and re-sell them the next night. ¥10 (September 2010).
