How many anime series do you know from japan?  

I do not think i know any. I might have seen one but if so i did not know it was japanese

I've seen many Japanese anime series in my time...
When I was really young I was watching "Candy" and "Sandy Bell", then it came the time for "Sailor Moon", "Grendizer", "Voltron", "Macron 1", and further on, "Dragon Ball Z" until today when I like watching series like "Inuyasha" or "YuYu Hakusho".

i know a lot of them such as ghost fighter, dragon ball z, samurai x, flame of recca... there are many...

hmm... here are the lists of animes I know:

* dragon ball, dragon ball Z, etc.
* astroboy
* yu-gi-oh

there's so much more, i forgot some of their names... once i remember them, i'll post it here!

There are a lot of anime around, depending on which genre you're into. It would take forever to list them down so I suggest that you visit www.animenewsnetwork.com since they have this encyclopedia that you can use to view synopsis, information and ratings of different anime. It's very helpful. I always use it whenever I see a new title ^_^

In my time I've seen:
Voltes V, Mazinger Z, Daimos, Samurai X, Dragonball Z, Flame of Recca, Ghostfighter, Zipang, Naruto, Sailormoon.
I'm not sure if you can count Samurai Jack in the list. :)

when i was a kid i was watching only two cartoons: Dragon Ball Z and Yu-Gi-Oh.

Wow, if you only know of Naruto, then you are missing out on a lot, a WHOLE lot. I know of many anime, since there are thousands, but those I have actually watched include:

Card Captor Sakura*
Chobits*
Cowboy Bebop
Digimon*
Dragon Ball/Dragon Ball Z
Flint the Time Detective
Fruits Basket*
Full Metal Alchemist
Gravitation*
Gundam: 8th MS Team
Last Exile*
Loveless
Ouran High School Host Club*
Outlaw Star
Pokemon
Prince of Tennis
Princess Tutu*
Revolutionary Girl Utena
Rurouni Kenshin
Sailor Moon
Sonic X
Tenchi Muyo/Universe/In Tokyo
Trigun
Yu Yu Hakusho*

I put stars next to my favorites, and this list doesn't include movies and OVAs (Original Video Animation) There are others that I have seen but these ones I have watched most of or all of and I also own several of them. You should check out some of these titles! Oh, and the anime people have listed called 'Ghost Fighter' is actually called Yu Yu Hakusho, Ghost Fighter is the name of the Filipino dub.

well I have have to many animes ever since i was just 6, it's hard to enumerate all, here are the animes that I know visit this site "mango-manga.cjb.net", including also live-action movies and series from japan...
