Double post to say the album is up for pre-order on US iTunes (and despite the single not being on iTunes, "Kono Machi" will be on the iTunes album). It's $12.99, though it might be best to wait: if you've already purchased the pre-album singles - as I did - there might be a "Complete My Album" option for a cheaper price once the album if officially released (the album page already shows me as having purchased four of the tracks on the album).
