I wrote about Gujo-Hachiman here and have added some photos.
Trains from Tokyo to Gujo-Hachiman include the super fast shinkansen (bullet train) and the ambling single carriage local train that finally takes you to the town.
Once in Gujo-Hachiman it’s time to slow down further, to stroll through the old part of town, admiring the centuries old wooden houses, the Shinto temples identified by their torii (entrance gate), to mingle with the relaxed locals, and find water everywhere.
Water is truly everywhere. The river flows through the centre of town, joined by numerous streams and canals descending from the hills. They provide the music of moving water, from tinkling and trickling sounds, to louder gushing, and the higher crescendo of the river’s waterfalls and runs.
After taking in the sights of town, a reasonably steep climb up the hill brings the visitor to the (restored) 16th century castle with its fine view over the valley and surrounding forested hills.
Gujo-Hachiman is a delight.
