I thought it was a common grass yellow butterfly at first but it's not so yellow and its spots, which should be black, are paler or nearly pale gray, which made me conclude it's a male cabbage white butterfly.
Although its English name and Japanese name (which translates to "spot white butterfly") both include the term "white," the male cabbage white butterflies are yellowish. Also, according to Kubota Corporation's website (in Japanese only), they can tell the male from the female by the wing color because they can see ultraviolet light. The female's wing, which reflects ultraviolet light, looks brighter than the male's wing, which absorbs the light.
