Maps of Ezo, Sakhalin, and Kuril Islands
This map was made by Fujita Junsai and published by Harimaya Katsugorō in 1854, around the time period when the Tokugawa shogunate started sending expeditions to the area of Ezo, Sakhalin, and the Kuril Islands. Russia was also showing interest in this area at this time. Place names are identified and indicated in the Japanese katakana characters (the angular Japanese phonetic syllabary). Various land and sea routes in the Ezo area (now Hokkaido) are shown in detail.
