Due to the Japanese policy of isolation at the time, western scientific knowledge only came to the island in the form of outdated Chinese works that had been translated by Jesuit missionaries in China . Asada developed methods for determining the orbit of the heavenly bodies of the solar system and independently discovered Kepler's third law . He cut optical lenses and constructed telescopes with which he u. a. watched the moons of Jupiter .
In Osaka he founded the Senjikan School of Astronomy. One of his students was the future astronomer Takahashi Yoshitoki .
In Asada's memory, the lunar crater Asada and the asteroid (12364) Asadagouryu were named.
