Typhoon No. 6 is moving toward the Kanto region with a closest approach expected on June 3, 2026 [3].
The storm threatens major urban centers and rural prefectures with severe flooding and record-breaking precipitation. Because the Kanto region includes the densely populated Tokyo metropolitan area, the potential for widespread infrastructure disruption and emergency evacuations is high.
Forecasters expect record hourly rainfall in Tokyo, with projections exceeding 50 mm in a single hour [1]. The storm is currently moving from Shikoku toward Kanto, where it is expected to make landfall on June 4, 2026 [2].
In southern Japan, authorities have issued a Level 4 flood-danger warning for Miyazaki Prefecture [2]. This warning indicates a high risk of flooding that could threaten lives and property, prompting local officials to urge residents to prioritize safety.
The typhoon's northwestward track is generating strong rain bands as it approaches the mainland [2]. These bands increase the likelihood of localized flash flooding and landslides in mountainous areas.
Emergency services are monitoring the situation as the storm progresses. Officials said the combination of the storm's path and the intensity of the rain bands creates a significant risk for the Kanto area over the next 48 hours.
“Tokyo expects record hourly rainfall, with projections exceeding 50 mm in a single hour.”
The convergence of record-breaking rainfall forecasts for Tokyo and high-level flood warnings in Miyazaki suggests a high-impact weather event. The movement of the storm from Shikoku toward the Kanto region puts the nation's primary economic and political hub at risk of significant transit delays and urban flooding, necessitating a coordinated national emergency response.
