Mothra!
I checked this out, it’s a rather minor tropical system at its peak and the track is considerably to the east of Tokyo, the JMA shows a landfall about 100 miles northeast of Tokyo at only a tropical storm intensity in 3-4 days, and the GFS model doesn’t show that landfall but has the storm circling around offshore instead. Probably the impact on Tokyo would be moderate northeast to north winds in the 30-40 mph range and some moderate rainfalls, disruptive to some events possibly, no big catastrophe however.
The more newsworthy tropical event is the other typhoon now approaching China (In-fa) looking like it might bring heavy rains to already flood-ravaged central China. That may be the bigger news maker of the two.
