Ino's surveys were done in 10 expeditions . The first survey started on June 11, 1800 and included 5 members. This survey was mainly to begin charting the coast of Hokkaido (where Russian ships had come to open trading houses). This survey was done almost entirely by measuring walking steps  and taking astronomical observations. They made it to Bekkai 別解 in far Northeast Hokkaido. In total they walked and surveyed 3,244 km. The results of the first survey, paid for almost entirely by Ino's own funds, helped the Bakufu government understand the significance of the work. For this reason, starting with the second expedition (departing Tokyo in the summer of 1801) he received more support, and the route was more ambitious, covering most of the Eastern seaboard from just south of Tokyo to the far northern tip of Honshu, and then the interior portion on the return trip. This expedition lasted approximately 6 months and covered 3,122 km. After the second survey, more and more trust was put in Ino's endeavor. By the fifth expedition, there were 19 people involved, they covered almost 7,000 km. On the 8th expedition they covered over 13,000 km in 914 days, most of it in Kyushu. By this time Ino was 70 years old, which was decades older than the average lifespan at that time. In addition to his maps, Inō produced scholarly works on surveying and mathematics, including "Chikyū sokuenjutsu mondō" and "Kyūkatsuen hassenhō". Inō is celebrated as one of the 'architects' of modern Japan. A museum, dedicated to his memory, was opened in his former home in Sawara, and in 1996 was designated a National Historic Site. In November 1995 the Japanese government issued a commemorative 80 yen postage stamp, showing Inō's portrait and a section of his map of Edo. Most of the complete copies of the atlas have been lost or destroyed (often by fire), although a mostly-complete copy of the large-scale map was discovered in the collection of the U.S. Library of Congress in 2001.
