Daiya Seto Comes Within .03 Of Lochte’s SCM 400 IM World Record


25-year-old Daiya Seto is in the form of his life, having taken double gold at this year’s World Championships in Gwangju, Korea. After topping the podium there in the 200m IM and 400m IM, Seto earned automatic berths for his home nation-hosted Summer Olympic Games next year, per the Japanese Swimming Federation selection policy.

But the man is doing anything but resting on his laurels, continuing to race and joining the International Swimming League (ISL) Team Energy Standard for its inaugural season. He also is just coming back from an intense high-altitude training camp in Flagstaff, Arizona.

Entering these Japanese Short Course Swimming Championships, Seto said he was feeling particularly strong and ready to attack the SCM 400 IM record as a goal.

When the dust settled tonight on day 1 at the Tatsumi Interaintoaoi Swimming Center, the ANA swimmer indeed took the 400m IM gold in a time of 3:55.53, falling only .03 outside of American Ryan Lochte‘s World Record set at the 2010 Short Course World Championships in Dubai.

Seto’s previous personal best in the 400m IM rested at the 3:56.33 he put up at the 2014 Short Course World Championships. That represented the Japanese national record in the event, as well as the Asian continental record.

Tonight, however, Seto dropped that down by well over half a second to produce the fastest time of his career in 3:55.53 and nearly claim his 2nd SCM World Record. He already owns the 200m fly mark (1:48.24) from last year’s Short Course World Championships.

After his race, Seto told Asian media, “.03 is really frustrating,” in terms of narrowly missing the WR.

Breakdown of Seto’s Japanese national record and Asian record-setting swim tonight is as follows:

That is some swim. I can’t think of a more Lochte race than 4IM short course, to get within .03 of that shows Kalisz is going to need to pull it together this year to even challenge him.

not to mention how well the japanese swim in their home country, which is where the next olympics and WCs are

Kaisz should make the team first. It’s not granted.


True. He has to get through Litherland and maybe lochte in the 400, and Lochte and Andrew in the 200.

“falling only .03 outside of American Ryan Lochte‘s World Record set at the 2010 Short Course World Championships in Dubai.” lochte peaked in 2010-11, so seto going this fast is insane. the japanese always swim fast in their home country, so seto will be hard to beat over the next 2 years (not to mention seto’s great track record when swimming abroad)


Not messing around before Tokyo 😮
