Japanese Culture is a pretty cool thing, well not just Japanese culture but all of the Asian cultures are great (except for a certain few).
In my experiences I have been a part of a few cultures, those being the American culture and the Japanese culture, it is great to have the knowledge that I have about both. It makes me a bit more refined in some ways but then again I also have my faults when it comes to writing in English. I suggest studying a different culture in the future, be it from books or from actually going to those countries and experiencing it first hand. It just might change your view on both your life and the world as a whole.
