*** Quote from the website’s notes ***
“
The normal values are the 30-year average from 1991 to 2020.
(Note) Months with blank values indicate that there were no typhoons during the statistical period used to calculate the normal values.
(Note) Typhoons may approach over a period spanning two months, so the total number of approaches for each month does not necessarily match the annual total.
(Note) Due to rounding, the sum of the monthly normal values does not necessarily match the annual normal value.

(Note 1) “Formation” is based on Coordinated Universal Time (UTC).
(Note 2) “Approach” refers to instances where the center of a typhoon enters within 300 km of any meteorological office in Japan.
(Note 3) “Landfall” refers to instances where the center of a typhoon reaches the coastline of Hokkaido, Honshu, Shikoku, or Kyushu.

The horizontal axis represents the months (1–12), and the vertical axis shows the normal values for the number of typhoons that form, approach, and make landfall.
