Grand champion Hakuho said Monday he felt an "invisible weight" after suffering an arm injury in the final bout of the Spring Grand Sumo Tournament, where he racked up a record-extending 42nd top division title.

Hakuho pulled out another close victory in Sunday's bout against fellow yokozuna Kakuryu, but was seen holding his upper right arm and grimacing in pain after securing the Emperor's Cup.

At a press conference in Osaka, Hakuho said the injury was treated later on the night of his win and demonstrated his arm's limited range of movement by raising and lowering it in front of reporters, indicating a possible muscle tear.

"At any rate, I want to stay away from sumo and rest," Hakuho said.

The 34-year-old Mongolian powerhouse has now claimed at least one makuuchi division championship every year since 2006, when he won his first tournament as an ozeki. He ended the Spring meet with a record-15th undefeated record.

Meanwhile, at a press conference in Higashiosaka, sekiwake Takakeisho said he felt relieved to finally clinch promotion to ozeki, sumo's second highest rank.

"I feel truly relieved," Takakeisho said. "I had a chance come around and I wanted to see it through here."

The 22-year-old earned his 10th win on the final day of the Spring meet by sealing the fate of struggling "kadoban," or demotion-threatened, ozeki Tochinoshin, whose rank is in peril after he posted two straight losing records.

Takakeisho won his maiden top division championship at the Kyushu meet last November. He had met some of the criteria typically needed for promotion with an 11-4 performance at the New Year meet, but ended that tournament with a loss to ozeki Goeido and was overlooked.

"I couldn't show my power at a crucial moment," Takakeisho said. "I couldn't wait for the tournament to start so I could make up (for the New Year meet)."

With promotion forefront in his mind, the Chiganoura stable wrestler went 3-2 over the first five days of the meet, losing to komusubi Mitakeumi and fellow sekiwake Tamawashi as he struggled to rack up wins against the top-ranked fighters.

He rounded into form with five straight wins, including an upset against yokozuna Kakuryu, but lost to Hakuho and was then slapped down by Goeido, unable to exact revenge for the previous tournament.

"It was a shame, but I thought I should fight my type of sumo if I were to lose anyway," Takakeisho said. "It ended up becoming significant that I had this attitude."

The determined young wrestler said he was already thinking of the next step -- becoming the next Japanese yokozuna following the retirement of Kisenosato earlier this year.

"As a wrestler, it's natural to aim for the next rank. I have to go all out with a determination to win every single bout."
