Chiyoarashi Yoshinobu

Born in Kisarazu, Chiyoarashi began sumo training with his father beginning in elementary school. In his third grade of elementary school he met former Chiyonofuji, the then oyakata of Kokonoe stable.^[1] He then joined Kokonoe stable at the age of 15.

Debuting in March 2007, Chiyoarashi reached the salaried jūryō division in September 2011. He was promoted alongside his Kokonoe stablemate Chiyozakura [ja].^[2] In his first tournament in the division he posted an 8-7 score which saw him promoted to his career highest rank of Jūryō 10 in November 2011, but he failed to complete the tournament due to injury and posted a losing score of 4-6-5. He then sat out the next tournament in January 2012; when he returned in March of that year he was in the lower ranks of makushita.

He returned to jūryō in May 2013 at Jūryō 12, where he posted a score of 7–8. In the next tournament in July 2013, he was ranked at Jūryō 13, however, once again due to injury he had to withdraw on the last day, ending the tournament with a record of 4-10-1. He was forced to sit out three tournaments from November 2013 to January 2014; at his return he was in sandanme.

In March 2014, he won his first yūshō in sandanme in a playoff against Takakasuga, the two wrestlers achieving a perfect record of 7–0.^[3] By May 2015, he was in the upper ranks of Makushita but again was injured and had to withdraw from the tournament, and he sat out three tournaments from July 2015 to November 2016. He returned in January 2016 at the rank of Jonidan 32, and lost the yusho in a playoff to Kaito.^[4]

Between January 2017 and 2021, he wrestled consistently in the Makushita division, sitting out only one tournament in January 2021, due to a COVID-19 outbreak in his stable.^[5] The Japan Sumo Association announced after the November 2021 tournament that Chiyoarashi had been promoted back to jūryō, after an absence of 49 tournaments over eight and a half years.^[6] This is the longest time taken by a wrestler to return to jūryō in sumo history.^[7] He scored six wins against nine losses in his return to jūryō, and fell back to makushita after just one tournament. However, a 4–3 score at Makushita 1 East in March 2022 saw him promoted to jūryō again.^[8]

Chiyoarashi announced his retirement during the January 2024 tournament, after four straight losses in the makushita division.^[9]

Chiyoarashi was an oshi-style wrestler with his primary kimarite being oshidashi.^[10]
