Seiji Nakamitsu has used the pseudonum "Makoto Sugimoto" 杉本まこと (see this discussion).

I have corrected his pink film's credits to instead link to Seiji Nakamitsu (since my reports were unsuccessful over the past year). For this page, I have left 1 unconfirmed credit as Production Director for "L'Arc en Ciel LIVE IN U.S.A. at 1st Mariner Arena July 31, 2004"
