The Classics of Manga

What are the classics of manga, those titles that have been read by so many fans that new fans are quickly pointed towards them?

I've asked around, and here's the list I've come up with. In other words, if you want to get into manga, this should be a solid place to start. ;-)

Disclaimer: This list is incomplete, and I welcome suggested additions in the comments. Be aware that I'm looking for widely-accepted classics (that are available in English), as opposed to the merely popular. Update: Thanks to the Manga Critic for the suggestion and addition of Inu Yasha. Of course!

Slam Dunk by Takehiko Inoue or Prince of Tennis by Takeshi Konomi, just to round out representation from sports manga.

Fake by Sanami Matoh, to round out shounen-ai's representation on the list, as it's a little more representative of the category than Antique Bakery, though still very much loved.

Emma by Kaoru Mori, to maybe found out the seinen category by representing its occasional romantic inclinations.

When I posted a link to your list, readers offered a few other suggestions, including:

Banana Fish Full Metal Alchemist Kodocha Maison Ikkoku Ode to Kirihito Parasyte Uzumaki

FWIW, I'd definitely second the nomination for Parasyte; it's been around forever (or so it seems), and just about everyone I know has read it at some point.
