80th OSAKA HIGH SCHOOL SWIMMING CHAMPIONSHIPS
- Friday, June 20th – Sunday, June 22nd
- LCM (50m)
- Results
16-year-old Shin Ohashi already blew our minds on day one of the 80th Osaka High School Swimming Championships, firing off a new World Junior Record of 2:07.27 in the men’s 200m breaststroke.
But the teen wasn’t done, producing a monster outing of 59.03 to take the 100m breaststroke tonight.
Beating his competitors by over 4 seconds, Ohashi blasted a new Japanese National High School Record, hacking over half a second off the previous benchmark of 59.56. That former record was set by Yamaguchi Kanhiro over 12 years ago in 2012.
As a reminder, Ohashi led his 2:07.27 200m breast outing with a spicy 1:00.53, so we had a feeling something special was about to go down in this shorter distance.
Ohashi’s 59.03 fell just .02 outside of the longstanding World Junior Record of 59.01 Italian Olympic medalist Nicolo Martinenghi put on the books at the 2017 World Junior Championships when he was 18.
Splits for Ohashi’s 59.03 included 27.35/31.68 to become his nation’s 3rd-fastest performer in history, again, at just 16 years of age.
Top 5 Japanese Men’s LCM 100 Breaststroke Performers All-Time
- Yasuhiro Koseki – 58.78, 2018
- Kosuke Kitajima – 58.90, 2012
- Shin Ohashi – 59.03, 2025
- Shoa Sato – 59.18, 2021
- Yamato Fukasawa – 59.24, 2025
Entering this competition, Ohashi’s season-best and lifetime best checked in at the 59.88 logged at the Canet stop of the 2025 Mare Nostrum Tour. That took place at the end of May, so in a matter of just weeks, Ohashi found a way to drop .85 off that stellar performance to now rank 4th in the world.
Prior to that performance, at this year’s Japan World Championship Trials, Ohashi turned in a mark of 1:00.64 to take the B-Final.

While the Japanese men historically have had major success in the 200m breaststroke, including 3 former world record holders, the nation hasn’t had a consistently solid 100m breastroker since the days of Olympic champion Kosuke Kitajima and later Pan Pacific Championships gold medalist Yasuhiro Koseki.
Ohashi’s rapid emergence is a positive sign for Japan, both from an individual perspective as well as from a medley relay standpoint.
As we reported, Ohashi did not make the nation’s roster for Singapore but will be present at the World Junior Championships.
japan vs china in a 4×100 br relay -who would win?
Italy pretty good too
If it’s 100brst definitely China.
China wins the 400 japan wins the 800
his stroke rate is insane (especially for the 200br)
Kind of sad that the most recent Shackell nonsense seems to have drawn so much more interest than this guy’s two out of this world swims have.
lol his time would have won gold in Paris.
Is he going to Singapore?
Not barring a pretty dramatic change of plans: https://swimswam.com/amid-relaxed-standards-japan-reveals-34-strong-world-championships-roster/
Have they change plans before?
Not that I can recall. I’m sure it’s happened at some point in history. I wouldn’t count on it.
Timing is unfortunate.
But I placed him to win 100-200 br gold in 2028 LA
Soon this guy will be the first junior to go 58, and he will be a junior till 2027. Its scary to think where he going to be if he keeps improving until his early 20. Lets hope its not his peak
Campbell Mckean went 58 and he’s 18???
Depends on whose definition of “Junior” you use. World Aquatics, because he turns 19 this year, doesn’t consider McKean a “junior,” though USA Swimming might.
Thats why i used the word junior insteady 18 and under
Campbell McKean is not a junior according to WAQ
I think the Japanese team should let him go to Singapore…
I smile everytime I see Kosuke Kitajima’s name mentioned (in a list or otherwise). kudo’s to the young man for getting closer and closer to the Frog king’s time, I’m sure he’ll get it soon!
