The white flag bears a blue sixteen-pointed compass rose with a central double ring enclosing a Japanese character. Jan Mertens tentatively identifies it as the first character of the company name. The website includes the logo and an actual flag at a launching in Mare, volume 23; the magazine’s funnel photograph is partly obscured.
