Being alone in the dark, all that sounds is crickets. from that we begin to think how to be bright, the only way is to get up from down to be upright to live it, when I am in a cave. The people around this place called the Japanese cave, whether this was the first Japanese heritage cave, the place was dark and humid dominating the atmosphere inside the cave. and the size of the cave is quite large coupled with air ventilation in several angles, so the atmosphere inside the cave is not stuffy. Long corridors and many intersections in the cave were quite confusing for those who first entered the cave. This cave is located in Blang panyang-aceh north-indonesia, maybe this cave is a relic of the Japanese colonial era first, because Japan had colonized Indonesia in ancient times before the Dutch colonization came, because this cave was named (Japanese cave).
