You may have come across the tunnels on the highways or on the mountain bed or on the railway tracks. These tunnels were generally dark with small street lights in about 20-30 meters interval.
But have you ever imagined a tunnel which glitters? Yes this is true and it has happened recently in Japan. Recently in Japan, during a winter festival the authorities of the park has decorated the
whole park using the LED lights which has turned it into a glorious place and the decoration of the park is made in such a way that the whole ground of the park looks like a tunnel being lighted up.
