Being very clever at mathematics, he went to Tokyo to learn the surveying technique from Ino Tadataka. After repeated incursions of Russians to "Ezochi", Edo shogunate gave him an order to explore the northern part of Sakhalin island. In 1809, he reached the north Sakhalin and showed that it is an island separated by a narrow channel. In 1828, he denounced a plan to export secretly a detailed Japanese map by von Siebold. He died in 1844. | |
