I agree.
Maybe it is like the American words finding there way into other countries where English is spoken, because it is seen as "cool".

I think English being used in Japan is a bit sad as it dilutes the Japanese language and makes it a bit less pure.

It would be a shame if, in the future, we all end of with some hybrid language that is a mix of different ones as I think the differences are what make the world more interesting - and I would also like to see Japanese culture and language preserved because it is so beautiful(although it would be useful if everyone understood each other!).
