Tokyo, July 26 (TIWN) Typhoon Nepartak, currently moving northward from the Pacific, is likely to make landfall on Tuesday on Japan's main island including Tokyo, where the Olympic Games are underway, authorities said on Monday.

Since Typhoon Nepartak is expected to move west and approach the eastern and northeastern parts of Japan, some Olympic events may be affected by the weather, Xinhua news quoted the Japan Meteorological Agency as saying.
