Part of the challenge of booking events in Japan for an outside promoter is picking the right venue in the right city, making sure there is access for fans to public transportation and that you'll actually be able to sell tickets to the show. It's Showtime has already announced that in September they will be heading to Japan for their first "It's Showtime Japan" show. Don't get confused, because there have been "Countdown to It's Showtime Japan" events held in Japan, co-promoted by REBELS Muay Thai and M-1 Muay Thai in Japan, but this event will be the first fully-fledged It's Showtime event to happen in Japan.
It's Showtime has decided to head to Yokohama, the second-most populated city in Japan and home to quite a few big sporting events. Many K-1 events have been held in Yokohama, but in the 17,000+ seat Yokohama Arena. Instead, It's Showtime is setting its sights on a more modest venue, the Pacifico National Convention Hall of Yokohama, which seats around 5,000 people. For a first show in Japan with a brand like It's Showtime, booking a venue of that size is a good move, as if there is a lot of demand for tickets, there will be a buzz created, and no matter what they should be able to fill the venue up, depending on the names booked for the card.
There have also been some pretty intense rumors about this possibly being a co-promotion between It's Showtime and EMCOM's K-1, but nothing official has come out yet.
