Some reccomendations, and links to Japanese stuff. Easy to find in English and fun to look at in Japanese.
Welcome to the NHK - Japanese shut in conspiracy (NHKã«ã‚ˆã†ã“ã! - 日本ã²ãã“もりå”会)
Funny one about a shut in who has to learn from a little girl and his twisted life.

Funnything about the site, it asks if your still worthless (ã‚‚ã†ã ã‚ã ?) and if you pick yes, it takes you to the show site, and if you pick no you go the site of the fictional anime upon which the main character blames his problems / worships.
Sayonara zetsubo sensei (ã•よãªã‚‰çµ¶æœ›å…ˆç”Ÿ)

Durarara (デュラララ!!)
A crazy little tale about how lives can get intertwined with rival color gangs, enchanted swords, and headless spirits from ireland. Yeah, thats really what its all about. Ikebukuro is a cool place.

Berserk (ベルセルク)
Classic one about a beast of a fighter and his little buddy who turns to one hell of a demon. Good story and not all goofy screen pause hair colored shouting when they fight.
