A craftsman who ground lensescompleted a telescope of his own.

Iwahashi Zenbei was born in 1756 in Wakihama Shinmachi, now Shinmachi in Kaizuka. In 1793 he completed a telescope called the Kitenkyo, which the shogunate's astronomers used during the Kansei calendar reform. The prefecture's designation notes say it was also used by Ino Tadataka. The surviving telescopes and observation and surveying instruments were designated Osaka Prefecture Tangible Cultural Properties in 2003.

The main house dates from 1861 and was registered as a national Registered Tangible Cultural Property in 2003. It is a private home.
