Plus-Tech Squeeze Box are a Japanese electronic music/shibuya-kei duo formed by Tomonori Hayashibe and Takeshi Wakiya.

The frenetic sound of their first album FAKEVOX (2000) is driven by rudimentary synthesized sounds and heavily manipulated samples from a variety of sources, including jazz, big band, light music, MOR, and funk recordings ranging from the late-50s to the mid-70s. Junko Kamada provides vocals throughout the album.

Their second album, CARTOOOM!, was released in 2004. Junko Kamada is conspicuously absent, having parted ways with the band. Instead, sampled vocals and a variety of guest singers are used.

They created a side project with the vocalist Tomomi Matsuda called Tropico Q in 2010. The group did covers of classic rock songs.
