Hakuho wrapped up another fruitful campaign with a hard-fought victory over veteran ozeki Kaio on Sunday, the final day of the New Year Grand Sumo Tournament.
The Mongolian, who secured his sixth straight Emperor's Cup and 18th overall on Saturday, was given a run for his money by crowd favorite Kaio (9-6) in the last bout of the 15-day basho, but he prevailed with a rear push out to finish with a 14-1 record at Ryogoku Kokugikan.
The lone yokozuna became only the third man in history to claim six straight titles, following Taiho, who achieved the feat twice, and Asashoryu, who holds the record with seven.
