FYI the release group has this down as "Moomin Dani no Okurimono", but based on retail sites etc. I'm assuming that it's a typo and should instead be "Moomon Tani no Okurimono".
I can confirm you it indeed is "Moomin Tani no Okurimono"
If you see the box, It says
"???? ?" = Moomin Tani = Moomin Valley
"?????" = Gift
So the title is "Moomin's Valley Gift" (Probs "Gift of the Moomin Valley" but whatever heh.), If it where "Dani" (??) It wouldn't make any sense.
Also the kanji next to Moomin ("?") It's Tani.
