A 42-year-old league that finally cracked 10 million fans — and why your trip to Korea isn't complete without one game.
If you've spent more than a week in Korea, you've probably noticed something strange. Bars hang giant team flags. Office workers leave at exactly 6:25 PM in jerseys. Convenience stores stack chimaek (chicken and beer) deals near the door from April through October. There's a reason for all of it, and it's called KBO — the Korea Baseball Organization. This post walks foreign visitors through how a league that started with six teams in 1982 became, in 2024, the first Korean professional sports league to ever pull in over 10 million fans in a single season. By the end, you'll know who to root for, what to expect at the stadium, and where the league quietly trips up newcomers.
What's in this post
What KBO actually is
KBO stands for the Korea Baseball Organization, founded on December 11, 1981. It governs the top professional baseball league in South Korea, also called the KBO League. Ten clubs play a long regular season — currently 144 games per team from late March through early October — followed by a five-stage postseason that ends in the Korean Series.
Foreign baseball fans usually arrive with one of two reference points. Either they think of Major League Baseball and expect a slower, more reverent atmosphere. Or they think of Japan's NPB and expect organized, polite chants. KBO sits somewhere else entirely. Imagine MLB-level talent at the top end (think Hyun-jin Ryu, Jung Hoo Lee, Ha-seong Kim), Japanese-style organized cheering, and a party atmosphere closer to a soccer derby. That's the rough picture.
1982: A league born from politics
The honest origin story is not a romantic one. In the early 1980s, the South Korean government under President Chun Doo-hwan wanted to redirect public attention away from political tension. The administration's so-called "3S Policy" — Sports, Screen, Sex — was an explicit strategy to keep citizens occupied. Professional baseball was the headline product. According to KBS World Radio's history archives, the league launched on March 27, 1982, with six corporate-owned franchises tied to specific regions:
- OB Bears (Chungcheong region, later Seoul → today's Doosan Bears)
- MBC Cheongryong (Seoul → eventually became the LG Twins)
- Haitai Tigers (Honam region → today's KIA Tigers)
- Samsung Lions (Daegu)
- Lotte Giants (Busan)
- Sammi Superstars (Incheon → many name changes, today's SSG Landers)
The first ever pitch was thrown at Dongdaemun Stadium in Seoul, between MBC Cheongryong and Samsung Lions. MBC won 11–7 in extra innings on a walk-off grand slam by Lee Jong-do — a moment now treated almost like a national folk story among older fans. Whatever the political motivations, the product worked. Within a season, regional rivalries had calcified into something deeper than any government PR plan intended.
The expansion era: 6 to 10 teams
The league did not stay still. Expansion came in waves, each one tied to the regional politics of where Korean baseball was underserved.
- 1986 Binggrae Eagles (now Hanwha Eagles) join, bringing the league to seven.
- 1991 Ssangbangwool Raiders are added — the eighth franchise. They later folded in 1999, with their place essentially absorbed by the new SK Wyverns.
- 2008 Woori Heroes (today's Kiwoom Heroes) become the first non-conglomerate-owned KBO club, run on naming-rights sponsorship instead of a corporate parent.
- 2013 NC Dinos join as the ninth team, based in Changwon — the league's first true expansion club in over twenty years.
- 2015 KT Wiz become the tenth franchise, based in Suwon. The current 10-team format is set.
- 2021 Following SK's exit, SSG Landers take over the Incheon-based franchise. They go on to win the 2022 Korean Series in their second season.
- 2024 KBO crosses 10 million regular-season attendance for the first time in its 42-year history, finishing the season at 10,887,705 fans (KBO official records).
- 2025 LG Twins defeat the Hanwha Eagles 4–1 to win the Korean Series — their second title in three years.
The 10 current franchises at a glance
You don't have to memorize all of them. But knowing which team owns which city helps you read the room. If you're staying in Busan and wear a Doosan jersey to a Sajik Stadium subway exit, you'll learn the meaning of silent disapproval very quickly.

Stadium experience: what foreigners actually see
The numbers tell one story. The seats tell another. KBO games last around three to three-and-a-half hours, but most of the noise has nothing to do with the actual play. Each team has a dedicated cheer squad with a male cheer captain on a microphone and a row of female cheerleaders on a raised platform. They lead synchronized chants, fight songs, and dances for every batter on the home team.
Every player has a personal cheer song. Not a generic at-bat song — an actual full-length chant the entire fan section sings whenever they come up to bat. New player gets traded in mid-season? Within a week, the cheer squad has written him a song, and forty thousand people know the words. According to the Korea Tourism Organization's recent coverage of the 2024 attendance boom, this style of fan participation is now one of the top three reasons foreign tourists report attending a KBO game.
Then there's the food. You can bring outside food into Korean stadiums — yes, including a full bucket of fried chicken from the franchise across the street. Beer in the stands costs around 5,000 to 7,000 KRW. Soju is typically not sold inside, but most fans BYO it from convenience stores. The 7th-inning seat-jumping cheer at Sajik Stadium (Lotte Giants), where fans turn orange plastic bags into balloon hats, is borderline iconic and worth seeing once in your life.
Things nobody warns you about
Most travel blogs sell KBO as a pure feel-good experience. It mostly is. But there are real downsides foreign visitors should know before showing up.
How to attend a game without stress
If you only have one shot at a KBO game during your trip, here's the practical order of operations that actually works.
Step 1: Pick a team, pick a city
Don't try to be neutral. Locals find it confusing, and the cheering setup makes it nearly impossible to enjoy the experience as a fence-sitter. If you're in Seoul, go LG, Doosan, or Kiwoom. Busan means Lotte. Daegu means Samsung. The more local you go, the more interesting the atmosphere.
Step 2: Book ahead, but not too far ahead
KBO tickets typically open one week before the game on Ticketlink. Set an alarm. Use a credit card that supports international payment (Visa or Mastercard works for most foreigners). Tuesday and Wednesday games are far easier to book than weekend games, and they have the same atmosphere with smaller crowds.
Step 3: Arrive 60–90 minutes early
Pre-game is half the fun. Stadium plazas usually have food trucks, jersey shops, and photo zones. Sajik Stadium in Busan even has a small museum about Lotte Giants history near the main entrance. Arriving early also gives you time to figure out which gate matches your seat — Korean stadiums use a gate-then-section system that confuses first-timers.
Step 4: Buy the cheering stick
Inflatable thunder sticks (sold inside the stadium for around 3,000–5,000 KRW) are not optional. They're the entry ticket to the cheering culture. Without them, your hands have nothing to do during songs, and you'll feel exposed.
Step 5: Just copy the person next to you
Lyrics in Korean? Don't stress. Watch the cheerleaders' arm movements. Match the clap rhythm. By the fifth inning, muscle memory takes over. Locals notice foreign fans trying, and most will smile or even teach you a chant.
Final Thought
The first time you walk into Jamsil Baseball Stadium on a Friday night, something feels off. Not bad — just off. You came for baseball. What you walk into is a concert.
There's a man on a platform in front of your section. He has a microphone. He's not the announcer. He's the cheer captain, and for the next three hours, he's basically your conductor. The crowd doesn't watch the game quietly the way you might be used to. They sing. Every single batter has their own song. Yes, every one. And the stranger sitting next to you will absolutely glance over if you don't at least try to clap along.
You'll fumble the first inning. That's normal. Most foreigners do. The thunder sticks feel awkward in your hands. The lyrics are in Korean and they fly by fast. By the third inning, you've kind of figured out the clap pattern. By the seventh, you're shouting the name of a player you couldn't pronounce two hours earlier. By the time the game ends, you understand — physically understand — why this league pulled in over 10 million fans in 2024, the first time in its 42-year history. The baseball isn't really the point. Or it is, but it isn't only that.
Honestly, the scoreboard is almost secondary. What you came for, even without knowing it, is the feeling of being one of forty thousand people losing their minds over a single. Order the chicken. Drink the cheap beer in the plastic cup. Just don't sit in the wrong cheering section unless you're ready to switch loyalties for one night.
Pick a team before you go. Any team. It doesn't matter which. The moment you have a color to wear, KBO opens up. And once it opens up, it doesn't really close again.
