Building a better working world
"Cultural and language barriers present formidable hurdles for overseas companies trying to break into the Japanese market. Therefore, I try to explain the issues involved as simply as possible, so it is easier for those companies to break into Japan and conduct business smoothly. In addition, I provide plenty of support to allow the start-up to focus on its core business."
