{{nihongo|Jimsaku|ジンサク|Jinsaku}} is a Japanese drum and bass duo formed by Akira Jimbo and Tetsuo Sakurai in 1990, after they left the jazz/fusion band Casiopea. They released 10 albums and one "Best of" collection, and disbanded in 1998.{{cite web |url=http://gonsiopea.com/artist/?a_idx=8 |title=JIMSAKU - Discography |publisher=Gonsiopea |access-date=May 18, 2024}} The name is a portmanteau of the two band members' last names, Jimbo and Sakurai.

==Founding and Early Jimsaku==

In 1989, Sakurai and Jimbo formed a band with members other than Casiopea, Shambara. Issei Noro called for Shambara to be disbanded, Sakurai and Jimbo refused and quit Casiopea, dissolving the original Casiopea. The two formed Jimsaku after this, wanting to be in an instrumental band again. Shambara fell apart, after Sakurai and Jimbo focused on Jimsaku instead.

Jimsaku's early discography was heavily influenced by Latin / Samba music after Sakurai's trip to Brazil in the early 80s influenced his style of music. Although this kind of music was different from main-stream fusion, Jimsaku remained popular. Jimsaku stuck to a two album annual release schedule, which put a strain on the quality of Jimsaku's compositions, forcing the two away from Latin music by the mid 90s.{{Cite web|url=https://www.discogs.com/artist/5973357-Jimsaku|title=Jimsaku|website=Discogs|access-date=August 13, 2024}} To try to fix this issue, any and all support members of the group were removed,{{cite web | url=https://blog.goo.ne.jp/jabe0755/e/e2cf406e4cf28fa4f1552fc7a74f8aa7 | title=舘ひろしさん、NHK SONGSの収録 with神保さん、櫻井さん、増崎さん | date=September 27, 2012 | website=Composer、Arranger、Pianist、Keyboard player、安部潤blog | language=ja | access-date=August 13, 2024 }} leaving just Sakurai and Jimbo. They instead invited singular artists to play with them on select tracks.

==Late Jimsaku and Disbandment==

Jimsaku has been featured on the "Mint Sessions" in 1997, a show where Sakurai and Jimbo talked with guests like the Members of Casiopea Second about the founding and early years of the original Casiopea.{{cite web |url=https://www.youtube.com/watch?v=xsUrbT3L1Vg&t=3979s |title=Mint Session |website=YouTube |publisher=bleach |date=June 15, 2023 |subject1=Issei Noro |subject2=Minoru Mukaiya |subject3=Yoshihiro Naruse |subject4=Tetsuo Sakurai |subject5=Akira Jimbo |access-date=August 13, 2024}}

Both of them played at the Casiopea 20th Anniversary Concert as "Support Drums" and "Support Bass".

Around this time, live performances shifted, after the support members left, concerts became just Sakurai and Jimbo on stage. With albums like "MEGA db", the band became very drum & bass heavy. in February 1998, Sakurai and Jimbo played a concert together not under the name Jimsaku, and announced the disbandment.
