Kanto Pass

Hi, I need some clarification on where the Kanto Pass is accepted. We are staying in Shinjuku and want to do a day trip to Karuizawa on the bullet train, spend a day sightseeing around Shinjuku and a day at at Daiba (or O'Daiba). Can someone please confirm that Daiba is part of the map for the Kanto pass or do we have to pay separately to get there. Just want to plan our days around the 3 day period to make the most of it. We are already doing a paid tour out to Mt Fuji so we won't be using it for that either. Thanks.
