Mark your calendars! One of Japan’s most beloved and fiercely competitive sporting events, the National High School Baseball Championship Tournament – affectionately known as “Summer Koshien” – is just around the corner!

For those unfamiliar with the passion surrounding high school baseball in Japan, picture this: nearly four thousand high schools across the nation dedicate themselves to intense training, all with the ultimate goal of reaching the hallowed grounds of Koshien Stadium. This iconic venue becomes the stage for a summer spectacle unlike any other.
Yesterday, July 29th, the final 49 representative high schools were determined. How did they earn their coveted spots? Japan is divided into 47 prefectures, and each one holds its own intense prefectural qualifying tournament. These tournaments are the ultimate battlegrounds, and only the champion of each prefecture earns the right to advance to the national stage.
You might be wondering why there are 49 teams when there are 47 prefectures. That’s because Tokyo and Hokkaido, due to their large number of participating schools, are each divided into two separate qualifying tournaments. So, two teams from Tokyo (East and West) and two from Hokkaido (North and South) join the champions from the other 45 prefectures, bringing the total to 49 elite teams.
Each of these teams has battled through grueling local tournaments, often in the sweltering summer heat, representing their prefecture with immense pride. To earn a spot in Koshien is a testament to their unwavering dedication, teamwork, and sheer perseverance. For many third-year students (the final year of high school in Japan), this is their last chance to achieve their lifelong dream. The weight of their school’s hopes and their own personal aspirations makes every game a dramatic and emotional rollercoaster.
These elite teams, having triumphed in their respective prefectural qualifiers, now step onto the national stage not just as players, but as the embodiment of their prefecture’s pride and honor. They carry the hopes of their entire region as they vie for the national championship.
The scale of this national tournament isn’t its only impressive feature; it also boasts a rich history. This year marks the 107th edition of the Summer Koshien tournament, meaning it has been a cherished event for over a century.
For the Japanese people, it’s a deeply ingrained summer tradition, an annual highlight that everyone looks forward to.
A Nation United by Youthful Dreams
While it’s true not every single Japanese person is a baseball fanatic, the Summer Koshien tournament holds a unique place in the hearts of many.
It’s a nationwide spectacle that captures the attention of millions.
High school baseball games are broadcast live on national television, offering real-time coverage.
Beyond TV, you’ll find extensive coverage on radio, in newspapers, and across online platforms.
Even regular news programs dedicate special segments to “Today’s High School Baseball.”
Local TV stations and newspapers go even further, providing in-depth reports on their home prefectural teams.
It’s common for people who don’t follow professional baseball to still tune into Koshien.
There’s a strong tendency for individuals to closely follow the progress of the high school representing their hometown or prefecture, regardless of their general interest in the sport. Even those living far from their hometowns in big cities like Tokyo or Osaka often feel a strong connection to their “home team,” reflecting on their own roots. In this sense, Koshien generates an enormous amount of nationwide attention and emotional investment within Japan.
The Grand Send-off: A Community United
Before embarking on their journey to Koshien, these champion teams participate in special events that highlight the deep connection between the players and their local communities.
First, the teams often visit their prefectural governor’s office.
This is a formal occasion where they report their victory in the local tournament, express their goals and enthusiasm for the national competition, and convey their gratitude to the local citizens for their support. In return, the governor offers words of encouragement and motivation.
Just before their departure for the national tournament, the school holds a major send-off event called a “Sokoukai” (壮行会).
This is not just a casual gathering; it’s a grand assembly where the team officially reports their local championship win and shares their aspirations and goals for the Koshien tournament.
They express profound thanks for all the support they’ve received and ask for continued encouragement.
The audience primarily consists of school faculty, students, and parents, all united in their pride and anticipation.
During this powerful event, the school’s cheerleading squad, brass band, and traditional cheering section give spectacular performances, sending off the players with rousing cheers and powerful encouragement, truly fueling their spirit for the national stage.
It’s a testament to how the entire school and community rally behind their team.
