Plaza Japan Web Shop

Hey guys! I came across this website called Japanese Hobby Plaza Japan. http://www.plazajapan.com/ and I was wondering if anybody has any experience with them? I'm looking to buy some Danball Senki model kits and they're the only ones that I found that has a good stock.

Or if anybody knows of a web shop that sells Danball Senki do share your information! I'd greatly appreciate it.
