Hokkaido, Japan's northernmost island, has seen a significant surge in cockroach populations due to rising temperatures and "artificial environments" such as buildings and homes. According to the Japan Meteorological Agency, the average daytime temperature on Hokkaido has risen by 1.5 degrees Celsius over the past 30 years, reaching up to 35 degrees Celsius in some areas during summer. This warming trend is attributed to global warming. Residents like Makoto Watanabe, who lives in the town of Eniwa, have noticed the increase in cockroach populations, with some recalling that they were rarely seen on the island even 30 years ago when it was considered too cold for them to thrive.
