Shin Nihon Kikaku
Shin Nihon Kikaku is Japanese for New Japan Project.
SNK: Shin Nihon Kikaku Corp.
Since 1982, it is now widely known as SNK, but the full name was still present altogether until 1986, when it was dropped.
This is the same as the previous logo albeit the "SNK" wordmark is in its current blue color and "LEISURE SYSTEM" is removed from the "swishy" S on the left of the logo and the box behind it is white instead of black.
SNK: SNK GROUP
The logo from 1986 to 1988: it look like the previous one but testifies to the oficial change of the name of the company. In April 1986, Shin Nihon Kikaku Corporation officially became "SNK Corporation".
In 1988, the full name was officially removed from the bottom of the logo and was officially became simply SNK. The font of the company was changed into what it is today. The blue color was temporarily changed back to its red color during the period.
As of 1990, the logo is now known as what the company is today. The blue color of the wordmark returned and the "swishy" S is now fully removed for good since 1978. The company ditched the Playmore title in 2016 to refocus on pushing their gaming heritage in the modern gaming era, nearing the current company's 15th anniversary. They have also reinstated the SNK slogan 'The Future is Now'.
After they reacquired the assets of the original SNK brand, the company changed its name to SNK Playmore.
But later, SNK merged with Playmore in 2016 and the Playmore has shredded away.
