How capacity is counted here

The numbers in this article are for each venue's largest room, with chairs only, set in rows facing the front (theater style). Add tables or serve food, and the number goes down. At Hotel Sunroute Plaza Shinjuku, for example, the Fuyo room holds 250 with chairs only, but 150 for a standing reception.

Before choosing a venue, it is also worth asking whether that many people will really come. Even if your company runs large events at home, your first event in Japan may not need the same headcount. Conectando has seen many events that drew a small crowd the first time and never ran again (→ How to organize an event in Tokyo).
