Shirogumi is a unit grouping system used in conjunction with Akagumi. They are usually used as Coupling Units to cover songs on SKE48 and NMB48 B-side Singles.
This grouping system is also used in various media such as concerts (like the AKB48 Kouhaku Utagassen 2012), and variety shows (such as AKBINGO!).
JKT48 Kenkyuusei members are currently grouped into Akagumi and Shirogumi for concert appearances.
