Will Namibia vs Japan tickets bought on SeatPick be seated together?

Yes. When searching for multiple Namibia vs Japan tickets on SeatPick, you'll automatically be shown seats that are next to one another, so you don't need to worry about being split up. You have the option to disable the 'Seated Together' filter on the event page if you'd like to view every available listing, including seats that aren't next to each other.
