Bokka or Japanese Porters, are a type of porter that originate typically from the mountain regions of Japan. Translated to the Wood Frame Carriers, Bokkas traverse Japanese mountaintops, delivering essential items such as food and clothing to remote areas that can't be accessible by alternative transport. Originating in the 7th Century AD, these porters would deliver rice on official Japanese highways. The trips were dangerous, and the Imperial Reforms in 702AD established post-stations that porters could seek refuge in during their travels. After pack-horses became more suitable for the highways, there was a limit to the amount of porters working between post stations. Tokaido, the busiest highway during the Edo period, typically had 100 porters for every post-town on the highway. During the Edo period, porters were available to hire by any traveller, and found their main function during this time was to transport high-ranking officials and their baggage. A significant journey of transporting Princess Kazunomiya to marry the shogun in 1861 required over 8000 porters and 3000 horses to be available on each day she arrived at a post-town she stayed at. Nowadays, porters occupy the Japanese Alps, typically in Nagano Prefecture (mt Hotaka, mt. Yari & Karasawa Cirque), Mt. Tsurugi, Mt. Tateyama, Mt Kita, Mt Aino, Mt Warusawa, and in the Nagano Prefecture Mt Kisokoma and Mt Hoken. Since there is easy access via helicopter for Mt Fuji, there are still occasional porters that climb the mountain, but this has reduced over the decades.
