Jirokichi Suzuki, accompanied by his niece, Sonoko won the auction with a $300 million bid. At a press conference, Suzuki announces his plan to gather all seven Van Gogh's Sunflowers paintings around the world for a grand exhibition. The venue would be a purpose-built gallery in a cliff in Japan known as "Lake Rock", with the highest security and protection. Suzuki also announces the engagement of seven specialists, whom he called the "Seven Samurai", to oversee the exhibition and protect the Sunflowers.
