Collaborating Artists

Artists who work with us for clients around the world

Bringing about new possibilities in business and art, to Japan and the world.

It is no secret that the skill of Japanese artists and designers is respected around the world. However, surprisingly few have brought this skill to the international stage. The reason is that to utilize sophisticated skills, language ability must be just as sophisticated. Language is the circuit connecting Japanese skill with international business.

In 2014, Phase Six worked with manga artist Hayato Sakamoto to create the art for “Hoist the Flag,” the comic for official Transformers event BotCon 2014, which celebrated the 30 years of the brand’s history in America. This collaboration between a Japanese artist and American writer created a truly international work.

In the opposite case, we have also managed the work of overseas artists for Japanese media. We like to think that our business model has brought about new possibilities in business and art, to Japan and the world.
