After a 30-minute walk from Saino-ko Lake in a steady drizzle, we heard a lapping sound emanating from an unseen shore. A few minutes later, we were standing on a 2km long stretch of sand and wetlands that border the west side of Chuzen-ji Lake. No cars are permitted here, so it is quiet and clean. Access to Senju-ga-hama is basically limited to Eco-friendly buses, ferryboats, and by foot. Wavering clouds and mist hid parts of the mountains towering high above the lake.
