The bold colors of Germany and Japan are used in harmony. The traditional 3 equal bars mimic a performance bar chart to imply it's business association / intent. The frame of the logo reminds us of a coffee cup (top view), but also can be viewed as a search icon, which hits at the heart of the purpose of this event hosted by the German Chamber of Japan. The type is a classic sans-serif font dressed in business blue, and also allows for the event year to be boldly displayed.
