12127 Mamiya           Discovered 1999 Sept. 9 by K. Watanabe at Sapporo.
Rinzo Mamiya (1780-1844) was an explorer and surveyor of the northern area of Japan. In 1809, he reached the north Sakhalin and showed that Karafuto (Sakhalin) is an island separated by a narrow channel, now called the Mamiya strait.
