I’ve been to see FC Tokyo a couple of times and on both occasions they managed to squeak a one goal victory. The first match was a 1-0 win over Vissel Kobe and the second a more exciting 3-2 against Nagoya Grampus.
FC Tokyo play in quite a large stadium. It holds about 40,000 people but I don’t think that they every get anywhere near capacity as this photo of the kick-off shows:
