Hatachi ("Twenty Years Old") is Tackey & Tsubasa's debut mini-album, released under Avex Trax on September 11, 2002.

[1] The title of the album refers to the fact that both boys were twenty years old when the album was released; Hatachi (二十歳) means 20 years old in Japanese, and is the age at which the traditional coming-of-age ceremony takes place.

The PV starts out with Tackey holding a pocket watch while sitting in a dark and dreary room.

Scenes switch once again to show Tsubasa in a field with trees around him, holding the same pocket watch Tackey had in his hands.

Finally, Tackey stands in the pool of water, sunlight filtering from a window dries him off, and he walks out of the room.
