Career
He made his debut in 1915. His highest rank was ōzeki. He retired in 1930 and became a sumo coach.
Takahashi had a very large build from a young age.
When he was registered for military service at age twenty he measured in at 181 centimeters tall and weighed 80 kilograms. When he joined the Kokura artillery battery, his size was noticed by his commanding officer and he was released from service to enter professional sumo.
The expectations placed on Takahashi when he debuted in sumo are clear from the ring name of Kuganishiki (陸錦) that he was given. lieutenant combined one the characters of the recently retired Hitachiyama (常陸山) with one of the characters of the former ring name of the then current yokozuna Nishinoumi Kajirō II, which had been Nishikinada (錦洋).
From his entry into sumo in January 1915, he lived up to these expectations and rose steadily through the ranks.
In his fourth tournament in January 1917, at jonidan 12 he earned his first championship with a 5-0 record. On this occasion he would take the new ring name of Onogawa. In this tournament his record was 4-5 with one draw.
This was his first losing tournament in over six years of sumo.
He was demoted to jūryō 1 for the following January 1922 tournament. A 5-3 record was enough to put him back into makuuchi for the next tournament, where he would remain for the rest of his career.
His success continued and he rose steadily through the ranks of maegashira and a very strong showing of 9-2 at the rank of komusubi in May 1926 would see him promoted to sekiwake. All three of his sekiwake appearances were winning records and in his second and third tournaments at sekiwake he came in second to yokozuna Tsunenohana for the championship.
He was promoted to ōzeki for the following October 1927 tournament.
In his rise to ōzeki after his initial losing tournament in his makuuchi debut in May 1921, he had only recorded one more losing record in a span of over six years. Ironically, he would miss his entire first tournament at ōzeki due to a bout of influenza. Two tournaments after becoming an ōzeki he changed his name to Toyokuni because a sumo elder in Ōsaka sumo had the name Onogawa.
Two tournaments later, in September of the same year he was again the runner up for the championship.
The following tournament in March of that year, he would finally record his first losing tournament in the san"yaku ranks. Afterwards, he soon announced his retirement.
Upon retiring, Toyokuni would take the elder name Kokonoe and soon after became the head of Kokonoe stable, a previous incarnation of the current Kokonoe stable. Later on his health began to suffer and in May 1937 he was obliged to disband the stable and his wrestlers moved to Asahiyama stable.
He died in May 1942 at the age of 48.
