ITF-1, also known as Yui, was an amateur radio cubesat built by Tsukuba University of Japan.

It had a size of 100x100x100mm (without antenna) and was built around a standard 1U cubesat bus. The satellite's primary purpose was the raising awareness of space by providing an easily decoded signal to amateur radio receivers. ITF-1's mission was unsuccessful; no signal from the spacecraft was ever received, and it reentered Earth's atmosphere on 29 June 2014.
