This anime is the best, I recommend it to everyone! :D I love it more than anything, haha! XD However, there are some things that aren't very appropriate for kids to be watching in this anime. They swear sometimes, but nothing way too bad(damn, bastard, hell, crap, etc...). There are also some perverted jokes, such as Miroku who is a monk travelling with Inuyasha and co. that just about always asks for women to "bear his children." Sometimes characters will be unclothed in scenes where they are relaxing in hot springs and such, but they do not show any "parts" or anything. This anime also has some violence, a lot of violence. The anime revolves around collection the shards of the Shikon jewel and they usually have to fight demons that have them. Also, besides fighting there is also blood, but nothing too graphic in my opinion. When Inuyasha is on television, it usually has a PG or 14+ rating. I would say this anime is probably for kids 12 or 13 and up. :) This anime is amazing, and its heartwarming. :D YOU SHOULD WATCH IT!
PS Don't listen to the review Common Sense gave, it's pretty off... listen to mine or someone else's review.
