Typhoon Mireille, known in the Philippines as Typhoon Oniang, was the costliest typhoon on record, striking Japan in September 1991. The 20th named storm of the 1991 Pacific typhoon season, Mireille formed on September 13 from the monsoon trough near the Marshall Islands. It moved westward for several days as a small system, steered by the subtropical ridge to the north. The storm rapidly intensified to typhoon status on September 16, and several days later passed north of Saipan in the Northern Marianas Islands. Mireille intensified further after deleterious effects from a nearby tropical storm subsided. On September 22, the American-based Joint Typhoon Warning Center (JTWC) estimated maximum 1‑minute sustained winds of 240 km/h (150 mph), and on the next day, the official Japan Meteorological Agency (JMA) estimated 10‑minute sustained winds of 185 km/h (115 mph). The typhoon weakened slightly while turning northward, passing just east of Miyako-jima and later to the west of Okinawa. On September 27, Mireille made landfall near Nagasaki in southwestern Japan with winds of 175 km/h (110 mph), the strongest since Typhoon Nancy in 1961. The storm accelerated to the northeast through the Sea of Japan, moving over Hokkaido before becoming extratropical on September 28. The remnants of Mireille continued to the east, passing through the Aleutian Islands of Alaska on October 1.
