Kisenosato fell to his fourth straight loss on Wednesday, becoming the first yokozuna to suffer four consecutive losses from the start of a tournament in 87 years.
Kisenosato, the sole yokozuna competing, logged the unwanted record in a loss to rank-and-filer Tochiozan at Fukuoka Kokusai Center.
No yokozuna has opened a basho 0-4 since 1931.
