Jap!

Background
Jap! was an alias used by video game company EJ Corporation, owned by Kazuaki Hashimoto, who at the time developed unlicensed hentai games for the Super Famicom during the mid-1990s including the SM Choukyoushi Hitomi series.

(1995-1996)
Visuals: On a white background, we see the word "JAP!" in the Balloon Extra Bold font.

Technique: None.

Audio: A high-pitched voice yelling the name. Availability: Seen on the unlicensed SNES titles SM Choukyoushi Hitomi Bangai Hen 2: Maki no Love Love Panic and Riverse Kids.

Legacy: This is a controversial logo, not only because of the games it appears in, but also since the name is considered by some as a slur against Japanese people (although this wasn't intended by the company itself).
