William The Kyushu Shinkansen connects Hakata and Kagoshima in 1 hour and 17 minutes at speeds as fast as 260-280 kph. The trains need maintenance and a place to “sleep” when not in use. One is JR Kyushu’s Kumamoto General Depot in Uto City. Having often travelled by the depot, its scale and complexity has never failed to impress. With a total area of 200,000 square meters, it’s three times the size of Fukuoka Dome and contains 23 tracks. Tours are available. To apply, dial 096 (357) 7272, a number dedicated to tour applications. https://www.nishinippon.co.jp/item/n/323436/
