Typhoon Chan-hom Weakens to Tropical Depression After Landfall in Eastern Japan

Typhoons are notorious for their unpredictability, but the recent landfall of Chan-hom in Ibaraki Prefecture has left experts perplexed. The 15th typhoon of 2026 took a drastic westward turn, defying the norm and rewriting the record books.

For decades, Japan’s typhoons have followed a predictable pattern: they sweep in from the east, driven by winds around a low-pressure system over the Pacific Ocean. Chan-hom, however, was steered by winds around a stationary high-pressure system north of the Japanese archipelago – an unusual twist that caught meteorologists off guard.

The implications of this anomaly are far-reaching. Japan’s weather agency has long relied on computer models to forecast typhoon trajectories, but Chan-hom’s westward path raises questions about the accuracy of these predictions. As the country continues to experience more frequent and intense typhoons due to climate change, it’s essential that meteorologists revisit their forecasting methods.

The impact of Chan-hom was still being felt on August 12, with potential flooding and overflowing rivers predicted for the Tohoku region in the north-east and the Kanto-Koshin region, including Tokyo. The agency forecast up to 150mm of rain in these areas over the next 24 hours, as well as storm surges that could be observed in western Japan through Thursday.

Chan-hom’s westward path has significant implications for Japan’s changing climate. As a nation situated on the Pacific Ring of Fire, Japan is no stranger to natural disasters. However, the increasing frequency and severity of extreme weather events – including typhoons, heatwaves, and droughts – are a stark reminder of the country’s vulnerability.

Historically, Japan has experienced some of the most devastating natural disasters in recent memory, from the 2011 Tohoku earthquake and tsunami to the 1995 Kobe earthquake. The nation’s resilience is often cited as a testament to its preparedness and disaster response strategies. But with climate change on the rise, it’s essential that policymakers and emergency responders adapt their plans to address the shifting weather patterns.

While Chan-hom has weakened to a tropical depression, its lingering influence will continue to impact Japan for days to come. The potential for flooding and overflowing rivers highlights the ongoing risk of extreme weather events across the country.

Emergency responders must remain vigilant and proactive in addressing this new normal. With climate change driving more frequent and intense typhoons, it’s essential that Japan invests in infrastructure upgrades and disaster mitigation measures – not just reactive responses to individual storms. Recent initiatives aimed at reducing the impact of natural disasters demonstrate a growing recognition of the need for proactive preparedness.

However, more work is needed to address the root causes of Japan’s vulnerability – and Chan-hom’s westward path serves as a stark reminder of what’s at stake. The global community is witnessing an alarming increase in extreme weather events – from intense typhoons to Category 5 hurricanes. Japan’s experience with Chan-hom is part of a broader pattern that demands attention and action from policymakers worldwide.

Climate change is a reality that refuses to be ignored, with far-reaching consequences for global economies, ecosystems, and human populations. As nations struggle to adapt to this new normal, it’s essential that we prioritize climate-resilient infrastructure and emergency preparedness measures – not just in Japan but across the world.

For now, Japan will continue to navigate the aftermath of Chan-hom’s landfall, bracing for potential flooding and overflowing rivers. Policymakers must remain focused on addressing the root causes of Japan’s vulnerability to extreme weather events. In the coming weeks and months, we can expect more intense scrutiny of Japan’s disaster response strategies, infrastructure upgrades, and climate-resilient initiatives.

Chan-hom’s westward path has left an indelible mark on Japan’s meteorological landscape – but it also presents a critical opportunity for growth, innovation, and resilience in the face of climate change.
