If you have clicked on this article wondering what the K3-K4 Championship is, you are exactly where I was just a few weeks back. Despite following the tribulations of the K3, perhaps as my own team could end up there in the near future, this somehow slipped me by. Idly looking through Futbology stats on the train to work (everyone does this right?), I noticed a curio in the upcoming fixture of one of the K3 clubs… the label K3vK4 on the game. Even more so, the game was at 1400 on a Wednesday. As luck would have it, my schedule allowed for attending the game, and thus researching what at least to me, has been the K league’s best kept secret this season.

In Short

The championship is a straight knockout cup, with the initial 27 teams folding into a Round of 16, Quarters, Semis and then a Final. The first round saw 11 ties, 3 being all K3 affairs, and another 3 all K4. There was no seeding, so last season’s K3 runners-up started in the third round, while some teams were given a bye. The opening two rounds were both played on Wednesdays in May, with kick-of times varying from early afternoon (1400) to evening (1900). The tournament is set to conclude in September, being played at the stadium on the ‘home’ side of the bracket.

Round of 16 Siheung 1 – 0 Dangjin

And so it was, a mad scramble down to Siheung’s boutique stadium (it has 1 stand and the pitch is surrounded by a green fence), for a 2pm Wednesday Kick-off. The weather was overcast, but the accompanying breeze gave the game a pleasant air, as the teams got down to business. Both of these sides were K3, and the standard ticket price in was 10,000 Won, (half price for Siheung citizens), perhaps a little steep, but the Siheung set-up generally has everything but the stadium going for it. A small merchandise store outside, a very active social media team, and a dressing room door next to the home fans seating area!

If you have followed the K3 this season, you’d be aware that Siheung are a bit of a steamroller, in that they have won 10, drawn 2 and sit comfortably at the top of the league (they won it in ’24, and came 2^nd in ’25). To make matters even more predictable, the two sides met at Siheung just 4 days prior, with the home side seeing out a 2-1 win. Thus a similar result was inevitable, although it would be settled by an unfortunate own goal by Lee Seon-ho, although I did not see it clearly as you cannot see the right half of the pitch from the top of the Siheung home stand on account of the roof over the press and VIP section. It also proved top be the worst tie of the round, as Chuncheon dispatched Seoul Jungang 6-1 with a hat trick for Lucas Oliveria, Yeoju dispatched Sejong with a 4-2 winner in extra time, 2 games went to penalties, and 2 other games ended 3-2. In other words, this cup is entertaining!

The biggest concern of course is the kick off times, but 107 paying punters (children go free but there were not many in attendance), down from the usual average of 315 for the season. No surprise given the match timing, and it is a burden shared by the Korea Cup. However, the next round will be played on a Saturday!

Quarter Finals

The next round is due on June 13^th, and there is some potential for this to attract a bit of attention with the World Cup forcing a hiatus on the upper leagues. 3 of the ties are all K3 affairs, but a single K4 outfit remains, with Geoju Citizen travelling to Chuncheon FC. As for the tournament itself, it can be seen as a little underwhelming given that there is a likelihood of repeating existing league fixtures relative to the more open Korea Cup. However, it offers an opportunity for clubs in the K3 and K4 to get their hands on some silverware. The furthest any K3 side has made it in the past half decade in the Korea Cup was Ulsan Citizaen’s run to the 2022 Quarters, although there was the fairytale 2019 edition when K4 Hwaseong made it to the semis, and K3 (then National League) Daejeon Korail made it to the final. The new championship offers an opportunity for the small groups of dedicated lower league fans to witness success, and hopefully bring new interest in the lower tiers, which in turn will strengthen the foundations of the Korean football pyramid as a whole.
