Arawashi Tsuyoshi (荒鷲 毅, born 21 August 1986 as Dulguun Erkhbayar) is a former professional sumo wrestler from Ulan Bator, Mongolia.

At the 2002 junior sumo tournament, he impressed then active Kyokushūzan with his ability and soon afterward he entered Araiso stable.

He debuted in November of that same year in maezumō at the height of 183 centimeters (6 ft 0 in) and weighing 83 kilograms (183 lb).

During this time he studied the techniques of former yokozuna Chiyonofuji who long suffered from an easily dislocated shoulder.

Arawashi alternated between winning and losing tournaments before a calamitous 2–13 record in May 2015 saw him demoted back to the jūryō division.

In November 2016 he produced a career-best performance as a final day win over Shōdai saw him end with an 11–4 record and a promotion to maegashira 2 for the January tournament.

In this tournament he started with five straight losses but then defeated yokozuna Kakuryū on Day 6 to earn his first kinboshi.

He returned to the top division in November 2018 but after winning only one match he withdrew on Day 13 with a left knee injury, sending him back to jūryō.

At his press conference he said he had continuing pain in his knee, and that his fondest career memory was his Day 14 win over Tamaasuka in January 2014, which clinched his first kachi-koshi as a sekitori.

It was the first retirement ceremony held at the Ryōgoku Kokugikan since Oshiogawa (former sekiwake Takekaze) a year previously.

[11] Arawashi does not hold elder stock in the Sumo Association but is working as a coach in an unofficial capacity at Minezaki stable while deciding on his future plans.
