100266 Sadamisaki           Discovered 1994 Oct. 14 by A. Nakamura at Kuma Kogen.
The Sadamisaki peninsula, in the westernmost part of the island of Shikoku, is the narrowest peninsula in Japan. Extending some 40-km from Yawatahama city toward the island of Kyushu, it separates the Seto Inland Sea from the Pacific Ocean. It is home to the Ikata Nuclear Power Plant.
