His most famous works are the designing of the mascots Neppie[a] and Ripsea[b] of the Orix Buffaloes, the concept art for the Monkey Magic television series, and video game artwork for Hudson's Adventure Island series (1986), Motor Toon Grand Prix (1994), and Maximo: Ghosts to Glory (2001).
He attended a specialized school and was educated in industrial design and later music where he gained a lasting appreciation for The Beatles.
Creating his own studio company in 1986, Matsushita immediately signed a contract with ASCII to produce covers for the video game magazine, Famicom Tsūshin (subsequently shortened to Famitsū).
These in turn became business propositions for Matsushita to develop mascots for musical bands, sports leagues, and even commercial and industrial organizations.
Career highlights include: Matsushita is married to American-Japanese jazz singer Naomi Grace,[20] for whom he acts as producer.
