1088 Mitaka (prov. designation: 1927 WA) is a bright background asteroid from the inner regions of the asteroid belt. It was discovered on 17 November 1927, by Japanese astronomer Okuro Oikawa at the old Tokyo Astronomical Observatory in Japan. The stony S-type asteroid has a notably short rotation period of 3.0 hours and measures approximately 15 kilometers (9.3 miles) in diameter. It was named after the Japanese village of Mitaka.
