Don Fujii

On April 12, he teamed with Kikutaro to beat Hollywood Stalker Ichikawa & Magnitude Kishiwada to become the inaugural Open the Owarai Twin Gate Champions. On October 14, he added the Triangle Gate titles to his collection, teaming with Masaaki Mochizuki and Akebono to defeat the champions Masato Yoshino, BxB Hulk & PAC. On May 13, 2010, Fujii, Mochizuki and Akebono lost the Open the Triangle Gate Championship to CIMA, Gamma and Genki Horiguchi. On January 10, 2011, Fujii and Mochizuki defeated Naruki Doi and Gamma to win the Open the Twin Gate Championship. They would lose the title to Genki Horiguchi and Ryo Saito on February 6, 2011. On September 23, 2012, Fujii and Mochizuki, now representing the Kaettekita Veteran-gun stable, regained the title from Shingo Takagi and Yamato. They lost the title to BxB Hulk and Uhaa Nation on March 2, 2013. On June 14, 2015, he, CIMA and Gamma defeated the Jimmyz (Ryo "Jimmy" Saito, Genki Horiguchi H.A.Gee.Mee!!, and Jimmy Susumu) to win the Open the Triangle Gate Championship. On October 8, CIMA and Gamma formed a new unit called Over Generation with Eita, El Lindaman, Punch Tominaga, and rookies Takehiro Yamamura and Kaito Ishida. Don Fujii did not join the new unit despite holding the Open the Triangle Gate Championship with CIMA and Gamma. On November 1, he, CIMA, and Gamma defended the Open the Triangle Gate Championship against the Jimmyz (Jimmy Susumu, Jimmy K-Ness J.K.S., and Ryo "Jimmy" Saito), and vacated the titles afterwards.

When CIMA started the Typhoon stable, it caused the first split between CIMA and Fujii, as Fujii did not want to align himself with Susumu Yokosuka and BxB Hulk. He is currently aligned with Masaaki Mochizuki and K-ness as part of a "seniors" unit. The three of them had an Open the Triangle Gate title run, but upon losing the belts, K-ness stepped back into a lower card role in the promotion while Fujii and Mochi have been focusing on representing Dragon Gate in other promotions. In 2008, the duo added Magnitude Kishiwada to their ranks, and the trio would eventually win the Open the Triangle Gate Titles from Yasushi Kanda, YAMATO & Gamma on September 28. They held them until February 15, 2009, dropping them to Shingo Takagi, Taku Iwasa & Dragon Kid.

Fujii has spent most of his Toryumon/Dragon Gate career in heel stables. He was a founding member of Crazy MAX, as well as a founding member of Blood Generation. When Blood Generation ended in December 2006, Fujii signed on with Magnum TOKYO's Renaissance project. The project never went anywhere as TOKYO suffered a career-ending eye injury shortly after it started.

He was one of the original graduates from the Toryumon dojo. He was also one of the founding members of the Crazy MAX and Blood Generation stables. He made a few appearances in World Championship Wrestling as Sumo Fuji. He has wrestled as Karaoke Machine #1 at times as well. From 1999 until 2002, he changed his name annually. He first went from Sumo Fuji to Sumo "Dandy" Fuji, then to Sumo "Dandy" Fuji 2000, then to Big Fuji, and finally to Don Fujii.

Tatsuki Fuji (藤井 達樹 , Fujii Tatsuki) , (born July 6, 1970) is a Japanese wrestler for Dragon Gate, best known by his ring name Don Fujii. He was one-half of the inaugural Open the Owarai Twin Gate Champions and is also a former two-time Open the Twin Gate Champions with Masaaki Mochizuki. He was previously in the Crazy MAX and Blood Generation stables.
