Chiba Marine Stadium(千葉マリンスタジアム,Chiba Marin Sutajiamu?) is a stadium in Chiba City, Japan. It opened in 1990 and holds 30,000 people.
The official opening of the stadium was held on April 13, 14, 15 1990, when popstar Madonna opened her Blond Ambition Tour at the venue. The show was blighted by heavy rain and high winds, which led to the concert being dramatically scaled-back, as documented in her documentary Truth or Dare.
