Good location for conference and exhibition facilities.
Fair degree of English spoken.
Pay for a room with a view ... you'll get Tokyo Bay and Mount Fuji and it is spectacular.
Restaurants on site are pricey, but there are a whole bunch by the railway station stacked on floors in the Plena building, think it was, that will suit any taste.
PLEASE DO use the pool and sports club facilities, Club+Club, which, if you are an English speaker, isn't immediately obvious. It costs about 3,000 yen, but it's a wonderful facility and well worth the price.
