On Saturday, June 27, 2026, a professional Japanese baseball official game, “Yokohama DeNA Baystars vs. Yomiuri Giants,” will be held at Yokohama Stadium, one of Japan’s most iconic ballparks. This day will be “Lawson Day,” featuring special events produced by Lawson, a major Japanese konbini (convenience store) chain.
To celebrate this matchup, a luxurious support campaign has launched exclusively in Japan’s Tokyo Metropolitan Area (Tokyo, Kanagawa, Saitama, and Chiba). This is a rare chance to win not just game tickets, but also valuable opportunities to experience the “behind-the-scenes” of the stadium that are usually off-limits. Professional baseball is an incredibly popular sport in Japan, and watching a game at Yokohama Stadium (commonly known as “Hamasta”) holds a special meaning for fans.
