From Tokyo, fly to Kagoshima Airport (approximately 1 hour 45 minutes), which sits at the base of the Kirishima range — ryokan shuttles can collect guests directly. Alternatively, take the Kyushu Shinkansen to Kagoshima-Chuo Station (about 6.5 hours from Tokyo, 4 hours from Osaka), then transfer to the JR Nippo Line to Kirishima-Jingu Station. Local buses connect the station to the highland onsen villages, though many properties arrange private transfers.
