This is a pennant commemorating the Yokohama High School baseball team's championship victories at the Koshien Tournament. From top to bottom: 70th Spring Koshien Tournament (1998 = H10) ⇒ This was the tournament where pitcher Daisuke Matsuzaka excelled. 80th Summer National Koshien Tournament (1998 = H10) ⇒ The tournament where Matsuzaka led the team to consecutive spring and summer championships. This was a tournament filled with records, including the legendary extra-inning victory against PL Gakuen, the come-from-behind semi-final victory against Tokushima's Tokushima Commercial High School, and Matsuzaka's no-hitter in the final against Kyoto Seisho. 78th Spring Koshien Tournament (2006 = H18) ⇒ The team won with a record-breaking 21-0 victory in the final against Nagasaki's Seihou High School. This was found in my parents' home. My late father was a fan, and since my parents' home is in the town next to Yokohama High School, he obtained these. The top two are unopened with plastic covers. The bottom one is opened, but in good condition. This is a set sale. Please refrain from purchasing individual items. Thank you for your understanding. Please note that the items will be folded for packaging during shipping.
