- Their label is Toshiba EMI.
- It seems that the band name has no deep meaning, it only means the typical "acid man".
- Birthplace: Saitama
- Before, all the three of them were members of different bands. But after, Ooki and Sato decided to create a band together and after the high school graduation, Urayama joined too. The band started activities with the three of them plus another member, Shiibashi Takashi who was the vocalist (while Ooki was only the guitarist at that time).
- During the high school time, the band name wasn't "Acidman", but "LSD". LSD means "Lonely ??? Dreamer" (the ??? part seems to have been forgotten by the members too). The one who decided the names (LSD and, then, Acidman) was Takashi.
- The members are good friend with the members of Ellegarden, Straightener and The Back Horn.
- The clothes they use are all personal effects. They have no stylist either.
