Akihiko Tago (多胡 昭彦, Tago Akihiko^?) is a Japanese amateur astronomer.

He co-discovered several comets, including C/1968 H1 (Tago-Honda-Yamamoto), C/1969 T1 (Tago-Sato-Kosaka), C/1987 B1 (Nishikawa-Takamizawa-Tago).

He also discovered several novas, including [V1493 Aql] (Nova Aquilae 1999), [V2275 Cyg] (Nova Cygni 2001 no. 2), [V574 Pup] (Nova Puppis 2004), [V2467 Cyg] (Nova Cygni 2007) and [V459 Vul] (Nova Vulpeculae 2007 no.2).

In 2006 he was the first astronomer to discover a micro-lensing system outside the Magellanic Clouds and the bulge of our Milky Way. The star GSC 3656-1328 suddenly brightened by four magnitudes in two weeks time and returned to its normal brightness two weeks later. A red or a brown dwarf star passed exactly in front of GSC 3656-1328 and the gravity of the dwarf star directed more light to the observers on Earth.

He lives in Tsuyama, Okayama.
