A Tokyo school counts the mornings it can see Mt. Fuji: 22 in 1965, 170 in 2023
Students at a Tokyo elementary school have been recording how often Mt. Fuji is visible each morning. Their data show the mountain was seen on only 22 mornings in 1965, rising to 170 mornings in 2023. The increase suggests clearer skies over the decades, which the school attributes to improvements in air quality and reduced pollution.
