The Shio no Michi Trail starts in Itoigawa, on the coast of western Niigata about 350km northwest of Tokyo, where the mountains of the Northern Japan Alps meet the Japanese sea and travels inland for over 120 klms to finish in the famous castle town of Matsumoto, in Nagano Prefecture.
A shorter version of the hike – of 70klms – finishes at Shinano Omachi, 20 klms past the famous ski area of Hakuba – which – in summer -offers some of Japan’s most spectacular mountain scenery.
The JR Oito Line connects several towns between Itoigawa and Matsumoto, including Hakuba and Shinano Omachi, making it easy to hop on and off the train as required between walking stops or return to the trail start upon finishing the hike.
Located between two mountain ranges and the Sea of Japan, Itoigawa offers striking scenery.
In this single city, the elevation ranges from sea level along the coast to the 2,766m peak of Mt. Korenge.
Cycling, hiking, rock climbing, skiing, swimming, fishing, and onsen hot spring bathing are just a few of the exciting outdoor activities enjoyed in Itoigawa. Of particular note for onsen enthusiasts is Renge Onsen, which includes 4 rotenburo (outdoor baths ) located on a mountainside about 1,500m above sea level.
The climate in Itoigawa is warm and temperate, with summer temperatures averaging around 24°C in summer and 2°C in winter
Once considered an area quite difficult to get to from the main cities , access to the area since 2015 has improved dramatically, with the introduction of the Hokuriku Shinkansen (bullet train.)
The Hakutaka service on this line now takes just over 2 hours direct from Tokyo – on one of the most picturesque fast train rides in the country.
