Japanese IM Ace Takeharu Fujimori Handed 4-Month Suspension For Positive Test

The Japanese Anti-Doping Authority (JADA) has handed a 4-month suspension to 25-year-old swimmer Takeharu Fujimori for having tested positive for a banned substance.

According to the Japanese Swimming Federation, as well as JADA, Takeharu showed a positive reaction to banned substance ‘Osterin’ at an in-competition test conducted at a domestic meet held in May.

Per the USADA, Ostarine is the trademarked name for a Selective Androgen Receptor Modulator (SARM) that is not approved for human use or consumption in the U.S., or in any other country. In recent years, WADA has reported an increasing number of positive tests involving SARMs, and athletes who use these substances most likely obtain them through black market channels. (USADA)

Takeharu reportedly argued he used supplements given to him by a Japanese Swimming Federation trainer before the competition to help widen blood vessels and improve blood flow, but the supplements were tainted with the banned substance. (NHK)

The swimmer was originally suspended for 5 months, but after an investigation by the arbitration agency that received the petition from Takeharu, the suspension was reduced to 4 months. The suspension’s start date was July 26th, which means Takeharu’s ban will not prevent him from competing at Japan’s Olympic Trials held in April of 2020.

Through his agent, Fujimori stated, “I never imagined that a positive reaction would occur if I mixed with supplements that had been explained to be safe.”

Fujimori did not compete at this year’s FINA World Aquatic Championships.

At the Japan Swim in April of this year, Fujimori finished 4th in the 200m IM (1:59.36) and 3rd in the 400m IM (4:13.90). He did finish with the 400m IM bronze (4:17.88) at the Japan Open in May, which may be the meet at which he tested positive.

The JADA decision is posted below.

Fujimori is far from the first Japanese swimmer in recent history to have received a doping suspension from JADA. In March of this year we reported how 2017 World Championships bronze medalist Hiromasa Fujimori tested positive for methylephedrine. (We are checking on if Takeharu is related to Hiromasa.)

Prior to that, in March 0f 2018, another World Championships medalist, Junya Koga, tested positive for traces of ‘banned muscle-building substances’, which the Olympian denied having taken knowingly. The substances were later identified as selective androgen receptor modulators “LGD-4033” and “SARM S-22”.

We will continue to update this post as more details become available.

Unbelievable!! Why do these athletes continue to cheat? Although a 4 month suspension is a joke and not much of a deterrent. He can still compete in the Japanese olympic trials. The suspension in this case should be a minimum of 2 years.

Why do they “cheat?”

I mean, it’s their livelihood. I can’t really fault them. It’s certainly not “right” or “fair” but I understand the pressures.


Steve youre about to get downvoted to bedrock but I can sorta “get it” too


Only 4 hmm


Why is anyone associated with the Japanese NGB giving an athlete “supplements”?
