 As "yatai" regulations were implemented at the local level across Japan, Fukuoka's "yatai" operators created a trade association and were mostly unaffected.The number of "yatai" has dwindled in most major metropolitan areas, though leveled in the early 21st century in response to Japan's economic stagnation and "yatai"'s relatively low cost.Nonetheless, in Fukuoka prefecture, the number of carts has declined since the 1960s from 450 to just 100 as of December 2018.
