Observe geological wonders in Itoigawa and soak in Amakazari's secluded hot springs
Itoigawa sits at the northernmost mainland point of the Itoigawa-Shizuoka Tectonic Line or "Fossa Magna," a tectonic fault line that separates the eastern and western parts of Japan. It was the first location in Japan to be designated a UNESCO Global Geopark.
Start your drive with a visit to the Fossa Magna Museum to see raw jade and learn about Japan's geological history. Then, head to the Toya Observatory for beautiful views of the surrounding mountains. There are trekking options around the Itoigawa Salt Trail if you would like to spend more time enjoying the mountains. End your drive with a relaxing stop at the hot springs of Amakazari Onsen.
