Japan’s Record-Breaking Autumn Heat
Unprecedented Warmth in Japan
Recent announcements from the Japan Meteorological Agency (JMA) reveal that the nation has experienced its warmest autumn since record-keeping began 126 years ago. This extraordinary heat wave has delayed the arrival of the iconic autumn foliage, leaving both tourists and residents eagerly awaiting the stunning transformation of leaves into their brilliant fall colors.
Record Temperature Increases
Data from the JMA indicates that temperatures during September through November have soared by an astonishing 1.97 degrees Celsius above average for this period, marking it as the hottest autumn on record since data was first compiled in 1898. Major urban centers such as Tokyo, Nagoya, and Sapporo reported temperature anomalies of 2.4°C, 2.9°C, and 1.2°C above seasonal averages respectively.

Delays in Autumn Foliage
This unseasonably warm weather has disrupted traditional schedules for leaf peeping across Japan. For instance, a railway company well-known for its popular illuminated maple tours in Kyoto has extended their operational period due to slower-than-normal changes in leaf color.
Experts now estimate that optimal viewing times for vibrant foliage will occur later this season than previous years; predictions suggest peak foliage in Tokyo around December 5, while Osaka will see its colors approximately four days later on December 9.
An Extended Summer Effect
This year’s atypical warmth follows what was already one of Japan’s hottest summers on record—an alarming trend that continues without respite. The impact of such extreme temperatures can also be observed at Mount Fuji, where snow coverage arrived notably late this year; it made its first appearance only in early November compared to October’s usual timeframe.
Climate Change Implications
The ongoing warming phenomenon observed within Japan mirrors global climate shifts where experts caution against an increasing frequency and severity of extreme weather events attributed to climate change itself.
Similar patterns are evident elsewhere; Australia recently recorded its warmest spring ever documented with temperatures climbing to an average increase of 2.08 degrees Celsius over typical values.
