Touko figure from Kara no Kyoukai. God, I love this one. It's so bloody cool. Her cigarette though is like the smallest accessory you'll ever see on a figure, so if you drop it on the floor or something, chances are you'll never find it again. Very easy to lose!
Shiki figure, also from Kara no Kyoukai. This one and the Touko one actually came as a set, and at significantly less of a cost than I paid for a lot of the other figures by themselves, despite the box and the figures being new and unused, so it was a real bargain. And buying figures in Japan is way cheaper than buying them online and importing them to begin with.
Aoko figure from Mahoutsukai no Yoru. After buying this one I actually eventually noticed that I find the face to be a bit meh.
Normal and Limited Edition versions of a figure of a Tony Taka character from...Shining Hearts, I think it was? Bloody sexy (and cool. I love the pose and her hair) in any case. Couldn't decide on just one, so I bought both. Though I think I like the normal one (the blue/black/silver one) slightly more than the (pink/white/golden) limited edition one.
Sasuke figure (from Naruto, duh).
Naruto (grownup Hokage version) figure. Fairly small, but, you know...Not that many half-good Naruto figures around...
Ichigo figure (from Bleach, duh).
Another Tony Taka figure. Seraphim something. Can't remember what work this one is from/is based on. I just really liked it, and thought it was awesome, so I bought it. This one is pretty big btw, especially what with the wings and the bow. One of her arms and half of the ribbon in her hair broke during transport, so I had to glue them back on with superglue. :-/ Thankfully it doesn't really show. I think I did a fairly good job of fixing it.
Japanese versions of volumes 2-5 (I already had volume 1, Art Material, in English) of the Fate/complete material books.
Kara no Kyoukai The Animation artbook. This one is hands down the best anime artbook I've ever owned by some margin. Really good book. No bullshit, just lots of full-page colour artwork of characters and backgrounds from the series, many of which are both vibrant and dynamic. Can heartily recommend to any KnK fan.
Saber (Fate/stay night) Portraits artbook. Had the Rin one from before.
ufotable Unlimited Blade Works adaptation art/info book thing. For me this one was disappointing, since I was expecting an artbook, but it's really more of an info book, with the art that is there being 90% still shots from the anime, or concept art of the locations used in the show. If that's what you're looking for however, and you can read Japanese, then I'm sure this book has some interesting info. As usual they have interviews with some of the staff and voice actors as well, so, that at least should interest some people.
The Blend (Coffee Kizoku) artbook. Very good book imo.
Bunch of Da Capo artbooks.
Two Angel Beats! artbooks.
Bunch of Clannad artbooks.
Ghibli Museum book that I bought while visiting the Museum (if you're ever visiting Japan, then GO THERE! It is so worth it. Just remember that you need to buy tickets way (months) ahead of time online or through someone you know in Japan, and you can only go on exactly the day and time it says on your ticket).
(Small) Totoro (if you don't know who Totoro is, then I don't know what to say...) plush (Totoro plushes in Japan range from everything from tiny keychain ones up to ones as big as you. :-/ ).
A small plush of those soot creatures that appear in My Neighbour Totoro and Spirited Away.
Finally, something extra special. I bought this wooden Totoro clock from an old guy running a tiny temporary stall outside a temple during a festival while in Kyoto. It is handmade (by him), is fully working, and his daughter (which was with him selling things at the stall), who spoke some English (her old father did not), claimed there was none other exactly like it. It is by far my most treasured item from the trip, and I really really like it, which is why I was mortified when I discovered that one of the ears had broken off during transport (I packed it in several layers of bubblewrap, clothes and everything inside my suitcase, but those damn airport luggage people somehow still managed to damage it! The hell are they even doing to the luggage they are handling!?) Thankfully I managed to fix it with superglue as well.
Special bonus, not from my Japan trip, but something that I bought recently. English copy of episode two of the Kara no Shoujo visual novel.
