Fujinokawa Seigō (Japanese: 藤ノ川 成剛; born February 22, 2005 as Seigō Saitō (齋藤 成剛, Saitō Seigō)) is a Japanese professional sumo wrestler from Edogawa, Tokyo and wrestles for the Isenoumi stable. He is the son of former maegashira wrestler Ōikari, who also wrestled for the same stable.

Early career

Fujinokawa was born in Edogawa, Tokyo as the eldest son of former makuuchi sumo wrestler Ōikari. He began his sumo career at the age of five and attended the Komatsu Ryu Dojo in Tokyo.

He was unable to compete in national tournaments due to his light weight until his second year of junior high school. He was able to compete in national tournaments in his third year and won the All Japan Junior Sumo Championship as a team.

During his third year at Saitama Sakae High School, he captained the sumo club and achieved success by placing in the top eight in the All Japan High School Sumo Usa Tournament and in the top 16 in the National Sports Festival.

Due to his success in high school sumo, he received offers from several universities, but was advised by the tenth generation Koyama to enter sumo sooner, so he decided not to attend university but to join the Isenoumi stable. Fujinokawa later reflected, "I think I couldn't have joined at a better time than four years later. "

Professional career

On 11 December 2022, it was announced that he would join the Isenoumi stable and make his professional sumo debut in the January 2023 tournament, instead of waiting until he graduated from high school. At the shinjo promotion ceremony, he entered the ring wearing the mawashi that his father had used during his active career, and changed his shikona, which had been his real name in the preliminary rounds, to "Wakaikari," taking one character from his father's shikona.

In the July 2023 tournament, he won all seven of his bouts and defeated Asahakuryu in the deciding match to win the sandanme division championship. He was promoted to the makushita division in September 2023.

In his seventh makushita tournament in September 2024, he finished with a record of four wins and three losses in the west makushita second position, and after the seventh match, his promotion to jūryō was considered a certainty. On 25 September, the Japan Sumo Association decided to promote Fujinokawa for the November tournament. This is the 13th time in history that a father and son has been promoted to sekitori, and a first for the Isenoumi stable. At the press conference, he revealed that he was considering taking on his father's shikona "Ōikari" once he reached the makuuchi division.

In the November tournament, he entered as jūryō 13 east. He lost his first three matches before winning his fourth match by default against makushita Kamito. He then lost his following two matches to have a record of 1 win and 5 losses. He won his seventh bout against Chiyomaru, and then won four consecutive matches. He won his seventh match, but lost the remaining two days to finish with a record of 7 wins and 8 losses.

In the January 2025 tournament, he won four straight matches from day one, he then had his first loss before winning five straight matches, which put him in the running for the championship. On the eleventh day, he was injured after losing to his rival Shishi and was forced to withdraw due to a distal rupture of the left biceps tendon. He finished with a record of 9 wins, 3 losses and 3 rests.

In the March 2025 tournament, he was ranked jūryō 9 east, and had a winning record of 8 wins and 7 losses. In the May tournament, he was ranked jūryō 5 east, he finished with a good record of 12 wins and 3 losses despite being one win short of the champion Kusano.

In the July 2025 tournament rankings announced on 30 June, he made his debut in the makuuchi division, and it was announced that he would change his shikona from Wakaikari to Fujinokawa, the traditional shikona of the Isenoumi stable. He is the sixth wrestler to use the name "Fujinokawa," he is also the first rikishi from Kyoto Prefecture to enter the makuuchi division in 27 years since his father, Oikari, and the youngest makuuchi wrestler to do so, surpassing Hakuohō. This also marks the first time in nine tournaments since the January 2024 tournament that a wrestler with a shikona ending in "kawa" that is not derived from his real name has returned to the rankings. He was ranked 14th in the west maegashira division, he pushed out Hidenoumi on the third day to win his first makuuchi match. He continued to win, and on the 13th day, with a record of 7 wins and 5 losses, he was given a walkover victory when his opponent, Takerufuji, withdrew from the tournament. This meant that he had a winning record in his debut tournament.
