EponymEiji Yoshikawa

Yoshikawa is a crater on Mercury, near the north pole. It was named by the IAU in 2012 after the Japanese novelist Eiji Yoshikawa.[1]

S band radar data from the Arecibo Observatory collected between 1999 and 2005 indicates a radar-bright area along the southern interior of Yoshikawa, which is probably indicative of a water ice deposit, and lies within the permanently shadowed part of the crater.[2]

Yoshikawa is south of the slightly smaller Vonnegut crater.
