Doberman Infinity is a hip-hop collective from Japan. The group was founded in 2000 by MCs Takashi “KUBO-C” Kubo, Takashi “GS” Mutō, and Yūji “P-CHO” Nagano, all of whom were members of the rap group West Head. The lineup was soon completed by fellow rappers Tomofumi “MAB” Mabuchi, Tomonori “Tomogen” Murakami, and beatmaker Bachlogic. They began performing under the name Doberman Inc and released six studio albums between 2002 and 2011 before changing their lineup and re-emerging as Doberman Infinity in 2015. That same year, their studio debut The Line reached Number 5 on the Oricon charts. Doberman Infinity’s second full-length, Terminal, saw the light in 2016 via Toy’s Factory and peaked at Number 7. After signing with LDH Music in 2017, the group delivered their third LP Off Road in 2018, which featured the Top 10 singles “Do Party” and “Ano Hi no Kimi to Ima no Boku ni.” A compilation titled 5IVE arrived in 2019 and was followed by the standalone singles “2020,” “Infinity Zoo,” and “6 -Six” in 2020. Doberman Infinity returned once again in 2021 with the pop-tinged rap track “Konomama,” entering the Top 50 on the Japanese streaming charts. D.X (2025) is DOBERMAN INFINITY's 5th album to mark their 10th anniversary.
