Please descend toward the Milky Way Galaxy, the Solar System, the third planet “Earth,” at latitude 35°41′00.0″ N and longitude 139°46′48.5″ E (WGS84).
Be advised that near Dumbonet Systems there is a Metropolitan Expressway junction and the Nihonbashi River, so exercise extreme caution during descent. Depending on weather conditions, strong wind gusts caused by surrounding buildings may occur.
Please also note that certain areas of the Dumbonet Systems rooftop have limited load-bearing capacity. Carefully select your landing point. As the rooftop area is not particularly large, descend as vertically as possible.
Large spacecraft are requested to avoid placing weight directly on the building. Please dock alongside the eastern terrace without applying structural load to the main building.
