Regional climate variation is a key determinant of the abundance and distribution of organisms on Yakushima Island, a World Natural Heritage Site in Ja- pan. While long-term meteorological observations have been conducted at multiple sites on the island, relatively little meteorological data are available for the western part of the island. Here, we report on the air temperature, rainfall, relative humidity, vapor pres- sure, wind speed, and wind direction data measured between 2005 and 2014 at Nagata in the northwestern part of the island. The data are available at http://doi. org/10.6084/m9.figshare.11662368.
