They are the old Dattebayo group that subbed the Naruto anime as well as others. Later they changed their name to Taka.
They are the guys that do proper translations, they're not biased towards anyone. They do hard subs, meaning the subtitles are part of the video and you can't get rid of them.
What I liked about them is not only the fact, that they're not biased. It's also the fact that if they make a mistake, they admit it and re-upload the video with the correct translation. They even do subbing for the songs in the opening and ending. They're basically the best when it comes to subs for Naruto along with other anime they sub.
Now why they're closing well they said it's because of personal reasons.
This is their website: http://www.takafansubs.com/
One thing I forgot to mention. Apparently one or more members of Taka formed another group called "Kurama" and now they started to continue the subs for Naruto. However I wasn't able to find any proof if that's true or not.
Oh yeah i remember them now , yeah they changed their name later to Taka it was familiar to me but i just couldn't remember from where thanks lol XD .
Also yes they were the best it sucks that they are closing now i hope they really form this Kurama group because i intend to watch the anime from 627/631 and SP sucks hard but with how they made this episode and the correct subs it makes me think that Kishi maybe has something to do with this after his involvement in RTN .
