Staff WriterInternational Series Japan has the look of a proper Sunday scrap now, the sort where nobody sleeps especially well and every gust of wind feels like it has an opinion. Hongtaek Kim and Japan’s Shugo Imahira will wake up sharing the lead at 10-under-par after a blustery, untidy, thoroughly compelling third round at Caledonian Golf Club, just outside Tokyo.
What had seemed, at times, like Kim’s tournament to manage turned into a back-nine wrestling match with the wind, the golf course and his own nerve. By the time the dust settled, Imahira had joined him at the summit, Yubin Jang sat a shot behind on nine-under, and Australia’s Travis Smyth and India’s Karandeep Kochhar remained close enough to make Sunday feel crowded.
That is usually how these things should be. If a tournament has any decency, it ought to leave a few fingerprints on the leaders before the final round.
A leaderboard with teeth
Kim began the day one shot clear and, for a while, looked as though he might put a little daylight between himself and the rest. Instead, the closing stretch bit back.
He signed for a one-over-par 72, while Imahira’s 71 brought him alongside. Jang’s 71 left him one behind, and Smyth’s excellent 68 moved him to eight-under with Kochhar, who carded a 73.
In other words, International Series Japan has gone from a neat leaderboard to one of those crowded affairs where every hole on Sunday feels like a small referendum on temperament.
The conditions helped. So did the back nine.
Kim still stands after a bruising afternoon
Kim’s round was not the work of a man coasting. It was the work of a man hanging on with both hands.
After managing the front nine impressively, he stumbled on the inward half with bogeys at the 10th, 12th and 14th. On a calmer day that might have been enough to lose control of the tournament. On this day, in this wind, it merely meant the others could catch him.
He did not fold. That matters.
The Korean, chasing a second Asian Tour title and a first on The International Series, spoke honestly afterwards about how the conditions shifted under his feet.
“I played really well on the front nine, especially managing the wind, but the conditions changed on the back nine and I wasn’t able to adjust as well. That made things a bit more difficult.”
There was no grand declaration after that, no reinvention of the wheel, which is often a promising sign on the eve of a final round.
“My game hasn’t really changed much since round one, I’ve been playing solidly throughout,” he added.
“I just want to keep doing the same things, hitting fairways and staying consistent. There’s no need to change anything going into tomorrow.”
Kim also arrived this week with rather more going on in life than yardage books and swing thoughts.
“I was a bit unsure about how I would play this week. I’m just really pleased with how things have gone so far.”
There is something admirably uncomplicated about that. New baby at home, tournament lead in Japan, wind blowing the scorecards sideways. Golf rarely asks whether the timing suits you.
Imahira gives the home crowd a real chance
If Kim had to absorb the pressure, Imahira gave the tournament its most compelling local angle.
The Japanese star dropped shots on 14 and 15, which might easily have left him trudging to the clubhouse feeling as though the day had slipped through his fingers. Instead, he birdied the 18th and suddenly became the first home player with a genuine chance to win International Series Japan.
That changes the atmosphere of a Sunday. It sharpens it.
Imahira is no novelty act here, either. With 10 Japan Golf Tour wins and back-to-back JGTO Money List titles from 2018, he knows how to handle the business end of a golf tournament. He also won the Asia Pacific Open Golf Championship Diamond Cup in 2022, a title jointly sanctioned with the Asian Tour, so the stage will not feel alien.
He made it plain enough that the conditions were no picnic.
“The wind made it really tough today, it was swirling and we had some sudden gusts out there,” he said.
“I really wanted to finish at even, so it was nice to make that birdie at the end. I’m looking forward to going into tomorrow with the lead.
“My family is coming out to support me, which I’m really excited about. Once the tournament starts, I don’t get much time for parenting, so I try to be a dad as much as I can during the off weeks.”
That final-round pairing with Kim and Jang now carries real weight: experience, power and home expectation all in one group.
Jang waits just behind, and that is dangerous
One shot back is often the prettiest place to begin a final round. Close enough to strike, far enough back to swing freely for a while.
Jang occupies that space now, and he may be the most intriguing figure in the chasing pack. Still only 23, he has already built a reputation as one of Korea’s brightest young talents. After helping his country win team gold at the Asian Games, he turned professional in 2023, won twice on the Korean PGA Tour in 2024 and earned a place on LIV Golf last year.
He did not keep those playing rights for this season, but there are players who shrink after a setback and players who seem to become harder from it. Jang looks rather like the latter.
His third-round 71 was shaped by patience more than fireworks.
“I missed a few putts early on, and the wind started to pick up, so I knew it wouldn’t be easy for anyone to go really low. I just tried to stay patient and keep myself in the round. My shots weren’t at their best, but I was able to adjust towards the end, which helped me finish on a positive note.”
He knows Kim’s game well enough too, though familiarity has not distracted him from the obvious task.
“I’ve played with him [Kim] a few times, and he is a very strong player,” said Jang.
“Hongtaek hits it long and is very consistent. But tomorrow is already the final day of the competition, so I’ll just focus on my own game and try to win.”
That is the right answer, and probably the only useful one.
Smyth is the sort of player leaders do not want to hear about
Every packed leaderboard has one name the leaders would rather not see inching closer. In International Series Japan, that man may well be Travis Smyth.
His 68 was the low round among the contenders, and it was no isolated spark. Smyth is already second on the Asian Tour Order of Merit after finishes of third and fifth in the first two events of the season, and he wrapped up the Challenger PGA Tour of Australasia Order of Merit last month.
Form like that tends not to knock politely. It barges in.
He sounded like a player who trusts the current shape of his game, even if he has not yet found perfect rhythm this week.
“I just have a lot of belief in what I’m doing at the moment. You know, coming into this tournament, I was pretty unprepared. Like I didn’t practice much at all in those two weeks off, and felt very rusty at the start of the week, and even the first two rounds.
“I don’t know, just taking it one shot at a time. I’m not really thinking too much about the result, and just, as cliche as it sounds, it’s literally just one shot at a time. And trying to sort of get my feel back, honestly, because it doesn’t feel like the same me as it did, like, sort of last month.”
That may not sound menacing on paper, but golfers who stop worrying about appearances and simply keep moving tend to be awkward company on a Sunday.
Why this Sunday matters
There is more at stake here than a silver trophy and a pleasant handshake.
International Series Japan is the first event of the season on The International Series, the Asian Tour’s elevated series that offers a route into LIV Golf through The International Series Rankings. That gives this tournament a little extra voltage. Good finishes carry consequences beyond the week itself.
For Kim, it is a chance to land his first title on The International Series.
For Imahira, it is the opportunity to become the first Japanese winner of this event.
For Jang, it is another opportunity to show that a difficult spell can be turned into fuel.
For Smyth, it is the continuation of a run that is beginning to look less like a hot streak and more like the shape of a very serious season.
A final round built on nerve, not noise
The most interesting thing about this leaderboard is that nobody arrives at Sunday untouched.
Kim bent but did not break.
Imahira found a late birdie just when his round threatened to sag.
Jang stayed patient when the putts were not falling.
Smyth crept closer without ever sounding particularly alarmed.
That usually makes for the best kind of finish: not one built on swagger, but one built on nerve. And if the wind returns to Caledonian Golf Club, as it so often likes to, International Series Japan may yet become a contest decided less by brilliance than by who can keep their wits while the course tries to borrow them.
