Typhoon 15 made landfall in southern Ibaraki Prefecture around eight p.m. on Tuesday [2].
This event is a statistical anomaly for the region. It marks the first time a typhoon has made landfall in Ibaraki since records began in 1951 [1].
The storm touched down approximately 40 kilometers north-northeast of Choshi City in Chiba Prefecture [1]. The landfall was driven by moist air flowing from the Pacific and the storm's westward trajectory [1].
Weather stations recorded significant wind speeds as the system moved across the region. Kitaibaraki City reported a maximum instantaneous wind speed of 29.3 meters per second [3], while Utsunomiya City recorded 28.6 meters per second [4].
Heavy precipitation accompanied the high winds. Choshi City recorded hourly rainfall exceeding 30 millimeters [5]. Authorities warned residents of the increased risk of landslides, and urban flooding as the system continued its path.
As of Wednesday morning, the typhoon was moving west across Honshu [1]. Meteorologists continue to monitor the system as it traverses the main island, though the historic nature of the Ibaraki landfall remains the primary focus of the current weather event.

The landfall of Typhoon 15 in Ibaraki represents a significant deviation from historical weather patterns in Japan. Because the prefecture has avoided direct typhoon landfalls for 75 years, local infrastructure and emergency preparedness may be less adapted to direct hits compared to regions like Okinawa or Kyushu. This event underscores the potential for shifting storm tracks to impact areas previously considered low-risk.
