153 Teams Confirmed for Osaka Regional High School Baseball Tournament Draw
The 108th National High School Baseball Tournament’s Osaka regional preliminary draw took place on April 16 at Hotel Awinia Osaka, finalizing matchups for the first three rounds of the tournament, which will begin on April 4, according to the Osaka High School Baseball Federation (府高野連).
153 Teams Enter Osaka Regional Bracket
The draw involved 153 teams competing for 12 spots in the 108th National High School Baseball Tournament, scheduled to commence at Koshien Stadium in Nishinomiya, Hyogo Prefecture, on August 4. The Osaka regional tournament, organized by the Osaka High School Baseball Federation and Asahi Shimbun Osaka, is the largest of the 47 prefectural qualifiers.

Teams were divided into 153 slots across three rounds, with the first round featuring 153 teams, followed by 64 in the second round and 16 in the third. The top 12 teams from the Osaka regional tournament will advance to the national championship, which includes 49 other prefectural qualifiers.
Key Matchups and Regional Powerhouses
Notable teams in the draw include Nishinomiya High School, a perennial powerhouse that reached the 2023 national semifinals, and Osaka Toin High School, which won the 2022 Kansai League. The draw placed teams from Osaka’s 24 districts into regional brackets, with the top seeds determined by performance in the 2023 Osaka Prefectural High School Baseball Tournament.
According to the Osaka High School Baseball Federation, the top eight seeds were assigned based on their 2023 regional rankings, while the remaining teams were placed through random selection. This structure aims to balance competitiveness and fairness, though some analysts argue it may favor teams from Osaka’s more established baseball regions.
What Happens Next for the 153 Teams?
The first round of the Osaka regional tournament is set for April 20, with 153 teams competing in a single-elimination format. The 64 winners will advance to the second round on April 27, followed by the third round on May 4, where 16 teams will battle for the 12 spots in the national tournament.
Teams not advancing to the third round will still have opportunities to qualify through the Osaka Prefectural High School Baseball Tournament, which runs through May 20. However, the regional draw is considered the primary pathway for most schools.
Tournament Format and Historical Context
The National High School Baseball Tournament, established in 1915, is one of Japan’s most prestigious high school sports events. The Osaka regional tournament has produced numerous national champions, including Kansai High School, which won the 2019 title, and Ritsumeikan High School, a 2021 finalist.

The tournament’s structure has evolved over the decades. In 2020, the event was canceled due to the COVID-19 pandemic, marking the first time in its history. The 2023 tournament saw a record 193 teams participate in the Osaka regional bracket, though the 2024 number reflects a slight reduction in entries.
Why This Matters for Japanese High School Baseball
The Osaka regional tournament is a critical test for teams aiming to reach Koshien Stadium, where the national championship is held. Success in the regional tournament can elevate a school’s reputation, attract college scouts, and boost local community engagement.
For example, Nishinomiya High School’s 2023 national semifinal run led to a 30% increase in local youth baseball registrations. Similarly, Osaka Toin’s 2022 Kansai League victory generated significant media coverage and sponsor interest.
