The primary cause of Tokyo's rising temperatures is the sheer density of its built environment. Massive concrete structures and asphalt roads absorb solar radiation during the day and release it slowly at night, preventing the city from cooling down. Additionally, the "canyon effect"—where tall buildings block wind flow from the Tokyo Bay—traps hot air in narrow streets. Waste heat from air conditioners and heavy traffic further exacerbates the problem, creating a feedback loop where the hotter the city gets, the more energy is used to cool it.
