The sprawling township of MINAKAMI (水上), buried deep in the mountains of Gunma-ken, about 65km west of Nikkō, has become one of the hottest spots in Japan for adventure sports. No fewer than ten whitewater rafting companies, including Canyons, offer trips down the Tone-gawa. Other activities include paragliding, canyoning, abseiling, rock-climbing and a wide variety of treks, including the ascent to the summit of Tanigawa-dake (谷川岳; 1977m). To relax after all this, head to Takaragawa onsen (宝川温泉), famous for its mixed-sex bathing (though it also has separated baths) and its four huge rotemburo.

To reach Minakami, take the Shinkansen to Jōmō-Kōgen (上毛高原) from where the town is a twenty-minute bus ride. The tourist office is opposite the station.
