Typhoon Tokage, known in the Philippines as Typhoon Siony, was the deadliest typhoon to strike Japan since Typhoon Bess in 1982. The twenty-third storm to be named using an international list of names during the 2004 Pacific typhoon season, Tokage was the last of three typhoons to impact Japan from late-September to mid-October 2004. Typhoon Tokage began as a tropical depression near the Northern Mariana Islands on October 10. With very warm waters, the system started to undergo a rapid deepening phase early on October 13 and reached its peak strength on the 17th. Tokage made landfall over Japan on October 20, just before becoming extratropical.^[1][2]

Tokage was the 10th storm to strike Japan in 2004, making 2004 the largest year ever for the number of storms made landfall in Japan.^[3] The record until 2003 was 6 (1990 and 1993), but 2004 was 10.^[4]
