My friend and I walked to Minshuku Kaisei from the port (with luggage in tow). It is about a 10minute walk. When you see the red building... the entrance is located on the side where the parking lot it. The two people I met were very kind, limited english but good enough to help us with everything we needed. They have maps, brochures, and a lot of helpful information! Rooms were clean and no need to share bathrooms. My friend and I came extremely unprepared! but it was super fun because super prepared folk just got as wet as us. It rained so hard the trail (Shiratani Yunizu Gorge) was closed! so we ended up renting a car at one of the many nearby rental agency by the inn (my favorite part of my trip was driving the entire island). There is also a supermarket close to the inn as well as many cool souvenir shops! A little bakery is just around the corner, the staff can recommend many good places! Next time I am in Yakushima, I would love to stay here again!
