The ear-reddening game (Japanese: 耳赤の一局) is a game of go of the Edo period of Japan, played on September 11, 1846 between Honinbo Shusaku (black) and Inoue Genan Inseki (white). The game is probably Shusaku's most notable game as it contains the "ear-reddening move"—so named when a doctor who had been watching the game took note of Genan as his ears flushed red when Shusaku played the move, indicating he had become upset. Shusaku made a mistake early on in the taisha joseki, but would play well throughout the rest of the game to win by 2 points.
