Unfortunately they don't export out of Japan to individual sellers, but you can find some on Amazon for like $40. They were going for a modular/customizable take on this, so you can buy different inserts to put into the thing. There's also tons of stuff on Etsy you can buy (like additional inserts, accessories, etc.) for the notebook. They have it listed as 'Fauxdoris', MTN, or Traveler's Notebook.
