The record-breaking 41.1°C in Kumagaya was not an isolated incident but rather the culmination of a prolonged period of intense heat that gripped Japan in the summer of 2018. The country experienced an exceptionally long and severe heat wave, with temperatures consistently exceeding seasonal averages across many regions. Several factors contributed to this extreme heat, including a strong high-pressure system that lingered over the Japanese archipelago, suppressing cloud formation and allowing for intense solar radiation to reach the surface. The Foehn effect, which brings warm, dry air down from the mountains, also played a role in driving up temperatures in inland areas like Kumagaya.
Kumagaya's geographical location further amplified the heat. The city is situated in the inland region of Honshu, shielded from the moderating influence of coastal breezes. This lack of air circulation allowed temperatures to climb rapidly during the day, with little respite even during the evening hours. The urban heat island effect, caused by the concentration of buildings and paved surfaces in Kumagaya, also contributed to the extreme heat. These urban surfaces absorb and retain solar radiation, leading to higher ambient temperatures compared to surrounding rural areas. The record-breaking 41.1°C in Kumagaya was a result of the confluence of these geographical and meteorological factors.
The impact of the record-breaking 41.1°C in Kumagaya was far-reaching.

Factors Contributing to High Temperatures in Japan
Japan's susceptibility to extreme heat is not a random occurrence but rather the result of a complex interplay of geographical, meteorological, and anthropogenic factors. Understanding these factors is crucial for predicting future heat waves and developing effective mitigation strategies. So, what are the key drivers behind high temperatures in Japan? Let's explore the various elements that contribute to the country's sweltering summers.
One of the primary factors contributing to high temperatures in Japan is its geographical location. The Japanese archipelago is situated in a region characterized by a monsoon climate, with hot, humid summers and mild winters. During the summer months, Japan is influenced by a subtropical high-pressure system that brings warm, moist air from the Pacific Ocean. This warm air mass, combined with intense solar radiation, leads to high temperatures and humidity levels across the country. The geographical position of Japan, surrounded by water and influenced by oceanic air masses, plays a significant role in its climate patterns.
The topography of Japan also contributes to the distribution of high temperatures. The country is largely mountainous, with a central mountain range running along the length of Honshu, the largest island. This mountainous terrain can create localized weather patterns, such as the Foehn effect, which can significantly elevate temperatures in certain areas. The Foehn effect occurs when air is forced to rise over a mountain range, cools and loses moisture, and then descends on the leeward side as warm, dry air. This phenomenon is particularly pronounced in inland regions of Honshu, where cities like Kumagaya and Tajimi have recorded some of the highest temperatures in Japan.
Meteorological factors, such as the strength and position of high-pressure systems, also play a crucial role in determining high temperatures in Japan. When a strong high-pressure system lingers over the Japanese archipelago, it suppresses cloud formation and allows for intense solar radiation to reach the surface. This can lead to prolonged periods of hot, sunny weather, resulting in heat waves. The interaction between high-pressure systems and other weather patterns, such as typhoons and frontal systems, can also influence temperature patterns. Understanding these meteorological dynamics is essential for forecasting heat waves and issuing timely warnings to the public.
In addition to natural factors, anthropogenic influences, particularly the urban heat island effect, contribute to high temperatures in Japan. Urban areas tend to be warmer than surrounding rural areas due to the concentration of buildings, paved surfaces, and other human-made structures. These surfaces absorb and retain solar radiation, leading to higher ambient temperatures. The urban heat island effect is particularly pronounced in densely populated cities like Tokyo and Osaka, where the temperature difference between urban and rural areas can be several degrees Celsius. Mitigating the urban heat island effect through strategies such as increasing green spaces and using reflective building materials is crucial for reducing heat stress in cities.
Climate change is another significant factor contributing to high temperatures in Japan. Global warming is causing average temperatures to rise worldwide, and Japan is no exception. The frequency and intensity of heat waves have been increasing in recent decades, and this trend is expected to continue in the future. Understanding the role of climate change in driving extreme heat events is essential for developing long-term adaptation strategies. By addressing both the natural and anthropogenic factors that contribute to high temperatures in Japan, policymakers and individuals can work together to build a more resilient and heat-prepared society.
