Tomohiro's Railway Tour of China  Sekiguchi takes on the challenge of traveling 36,000 kilometers (about 22,369 miles) by railway throughout China. The path was designed by computer software, such that the route is an unbroken line, and not a single part of the route crosses another part of the same route. The trip is broken into two editions: Spring and Fall. In the Spring edition, Sekiguchi's trip begins by flying from Japan to Lhasa in Tibet, and ends in Xian - with a distance of 17,000 km. The Fall edition continues the journey, and ends with a combined 36,000 km traveled.
