Typhoon Grace (1954)

Typhoon Grace was a strong typhoon that severely impacted the mainland Japan, whilst the Ryukyu Islands also receiving minor damages. The fourth storm to be monitored by the Fleet Weather Central during the 1954 Pacific typhoon season, Grace was first monitored by the FWC as a tropical storm in the Philippine Sea on the night of August 11. The christened storm then kept its status while tracking northwestwards and due westwards. Two days later, the agency upgraded it into a typhoon before turning towards the Ryukyu Islands by August 14, where its eye passed just near Okinawa Island. Grace peaked as a Category 3 typhoon into the modern-day Saffir–Simpson scale two times; upon entering the East China Sea and just near landfall over the mainland Japan. Upon doing it so, it rapidly weakened and degenerated into a low-pressure system on August 19. However, the JMA tracked the storm's remnants until August 23.

Airplanes from the 307th Bomb Wing were flown into the Philippines to escape any damages from the approaching Grace and Americans on Okinawa were asked to shelter. Only minor damages occurred there, but one person was killed and 10 other suffered injuries. Disruption were also confined to electricity and water supply being lost and huts being wrecked. Ships around Formosa, and troops over the Korean Peninsula were also warned about the storm. Landslides from heavy rains caused over 20 people to be buried alive in Miyazaki Prefecture while many houses across Kagoshima Prefecture were either destroyed or inundated. Over 510 mm of rain were also received over the country's mountain areas. 191 vessels also received damages from the storm, as well as croplands. In total, over 28 were confirmed to be killed due to Grace across Japan, while 33 were to be unaccounted for. 15 more were killed over the Korean Peninsula's south when rough waves overturned a fishing vessel and three only survived.
