Does Japan have philosophy?

I grew up with a philosopher and theologian for a father.  He taught me about Heiddegar, Plato, and Kant.  I would then argue metaphysics with my best friend in high school.  But by the time I entered college, I had come to the solid conclusion that my feeble capabilities of logic and reason could never lead me beyond a certain point along the path to the Truth. One thing only I knew and that was that I knew nothing, and I didn’t know how to proceed after that. It has taken me eight years since then to figure out how to move on, and the search, which led me to Japan, has questioned my assumptions about what philosophy is.
