This hat was created to commemorate the "Biggest Martial Arts World Cup in History Dynamite! SUMMER NIGHT FEVER in Kokuritsu," held on August 28, 2002, at the old National Stadium as the first-ever martial arts event of its kind. This was a martial arts event that generated various buzzes, such as the cooperation of K-1, PRIDE, and Mr. Antonio Inoki, the first-ever martial arts event at the old National Stadium, the professional mixed martial arts debut of Olympic gold medalist Hidehiko Yoshida (who won the gold medal in the men's 78kg judo division at the 1992 Barcelona Olympics), and the fight between Mirko Cro Cop and Kazushi Sakuraba. Over 90,000 spectators watched the event outdoors on a midsummer night, and pay-per-view sales recorded 100,000 purchases, setting a new Japanese record at the time. This is a rare item created to commemorate the event, featuring a print of the Dynamite! logo, illustrations of Hidehiko Yoshida, Royce Gracie, Kazushi Sakuraba, and Mirko Cro Cop. Although it is over 20 years old, it is unused. We are looking for those who cannot forget the excitement and impact of that event, or those who are collecting Dynamite! merchandise! *Please understand that this is a hat stored by an amateur, and those seeking perfection or who are extremely sensitive should refrain from purchasing. *Please note that there may be oversights in our assessment of the product's condition.
