I recently read a travel log of a walker who took the 280 km Nagasaki Kaido. His name is Takuji Matsuo, who lives in Shimabara, Nagasaki. He was a Shimabara Junior High School principal and now serves as a Shimabara Castle Archive specialist. He visited shrines and temples, took notes and photos, updated local maps and news, documented folk stories while traveling. He divided his travel plans into several legs to suit his convenience, so the entire trip took a whole year to complete. The walking itself took only 17 days or 420,000 steps as per his trusty pedometer.
I was interested in his description of Hiyamizu (cold water) Mountain Pass, the Hakone Pass of Nagasaki Kaido, the most difficult and laborious route. It is sometimes called Pan Pass, because travelers scooped mountain water with a pan to soothe their thirsts. Yes, the pass was a hard one. He perspired intensely, but endured.He wrote that all the railroads and highways today come and go there under their respective tunnels and travelers enjoy a great view from above. Records show an elephant calf, a gift to a Shogun, passed here.
It's a straight line from Dazaifu / Tsukushino to reach Iizuka / Kurosaki / Kokura. Uchino is the station coming off the Pass and Matsuo, the writer, found happily, that Uchino retained its form the way they were during the Edo days.
A "Nagasaki Walk" is occasionally held like "Earth Walk" or "Peace Walk," in spring and autumn by children and adults alike, sponsored by local municipal governments or newspapers.
This spring (2013), the city of Kitakyushu where I live, had a one day Nagasaki Walk Event to commemorate its 50th Birthday with great participation by its citizens. The full official course was from Tokiwabash Bridge (the elephant on the way to Edo) to Koyanose Station, including the Magari Row of Pines. I'm sure the path the elephant took depicted by artist Jakuchu was the same one. Other shorter courses were respectively 12 km and 15 km.
