The trailhead was hard to find on Mt. Nakasaka. It was correct to go through the south side of Tenjinzan and climb up to Mikanyama where there is a steel tower. I parked my scooter at a hut in a mandarin orange field and climbed up from here. I climbed along the monorail, but if you follow the patrol route on the left side of the hut, you can easily reach the ridge next to the pylon. From the ridge, you can enjoy the view to the north. Walking along the ridge to the west, you will see the summit of Mt.Nakasaka. However, the bushes from this point on are very thick and quickly become covered with thieves’ weeds (kosendangusa). In tears, we gave up on the summit. Apparently, the other side of the summit is a mandarin orange field. I wonder where is the right way to climb?
