anime is expensive even in Japan but iirc not as expensive in most cases as in NA and EU. I could be wrong though, I didn’t really go into any anime stores while I was there.
Manga on the other hand is an entirely different story. Holy crap, I know translating, licensing and publishing rights for a rather niche product are contributing factors, but damn, NA gets shafted on manga. You’re talking at least $10 for a single tankobon volume. I’ll give an example: I recently bought the entire Kure-nai series (10 volumes) for $50 shipped from Japan. On the back they have their mandated retail price of 438JPY (8% sales tax brings it to about 473). At today’s exchange rate that’s less than $4.50. Never buying translated manga ever again.
Slightly unrelated, I’ve actually started finding that in most cases I enjoy the manga more than a given anime. Kure-nai for instance, as an anime is one big flashback from the manga. Murasaki is way better in the manga imo. She looks like a mini Shana, where in the anime she looks like Lilo from Lilo and Stitch.
