Japan Sees First June Typhoon Landfall in 14 Years

Typhoon No. 6 made landfall in Japan this month, marking the first time a typhoon has hit the country in June in 14 years ^[1].

This shift in timing suggests a deviation from historical weather patterns, potentially increasing the risk of early-season flooding and infrastructure damage in regions unprepared for major storms outside the typical autumn peak.

Professor Yoshihiro Tachibana of Mie University Graduate School said the current season is defined by three specific characteristics: typhoons are making landfall earlier in the season, the total number of storms is higher than average, and high sea surface temperatures are serving as the primary catalyst for their formation ^[1], ^[2].

Residents in the Kanto region expressed surprise at the timing of the event. A woman in her 70s said the recent typhoon arrived early and that she did not expect it to reach the Kanto area ^[1]. Another resident, a woman in her 60s, said typhoons are typically associated with September and questioned where the storms were originating ^[1].

Tachibana addressed these concerns by explaining that the locations where typhoons form are generally consistent. He said that storms cannot develop unless the sea surface temperature is high ^[1].

Meteorologists point to the influence of a super El Niño as a factor contributing to the elevated ocean temperatures ^[1], ^[2]. This warming trend creates the energy necessary for storm intensification and may explain why Typhoon No. 6 ^[1] reached the Japanese coast so early in the calendar year.
