Seems there may have been 2 different publishers, as the front pictures don't match completely. One says in the top left corner "NICHIGAKU Computer Assisted Instruction" and in the red bar below "日学CAI" and the other says "Seichi Personal Study System" with some unreadable Japanese text in the red bar.
Two rows of Japanese texts preceding "Seichi Personal Study System" are "企画" (planning) and "製作" (producing) therefore the red bar text means "planned and produced by Seichi Personal Study System".
