Part of the 2004 Pacific typhoon season

Typhoon Ma-on, known in the Philippines as Super Typhoon Rolly, was a powerful typhoon that produced record breaking wind gusts across the Tokyo Metropolitan Area during early October 2004. It was the strongest typhoon to hit the region since Typhoon Higos in 2002. The twenty-second named storm of the 2004 Pacific typhoon season, Ma-on was the second of three consecutive storms to hit Japan during the period between late-September to mid-October 2004.
