The Goodwill Dome is the home of the Seibu Lions. It currently holds 35,879. The dimensions from left-center-right are 328, 400, 328.
It originally opened up as a non-domed stadium as Seibu didn't add the roof until 1997. It was formerly known as Seibu Lions Kyujo or Seibu Stadium (1979 to 1997), the Seibu Dome (1998 to 2004), and the Invoice Seibu Dome (2005 to 2006).
