20th Century is one half of the Johnnys Jimusho group V6. The other half of the group is known as "Coming Century". V6 were seperated into these two units near the group's formation according the members age differences. 20th Century is generally known for participating in musicals and plays, whereas 20th Century is generally known for appearing in more TV dramas and such. These two units typically only release songs as their sub-unit names as B-sides on V6 singles. It is somewhat rare that a single will be released under the name of one of the sub-units, though it has happened.
