When Japan reopens to international travel, a treat awaits hikers, “forest bathers” and those who like getting close to nature. The newly opened Michinoku Coastal Trail runs for an astonishing 1,000km (620 miles) through four prefectures – Aomori, Iwate, Miyagi and Fukushima – in the Tohoku region of northeastern Honshu. The ends can be found in the cities of Hachinohe.
