Buddha

Here is a good film of The Buddha from YouTube Many Japanese claim to be Buddhists.

Buddha said that he wasn't the light, but could show "the path." Yet, in John 14:6, "Jesus answered (his disciples), 'I am the way and the truth and the life. No one comes to the Father except through me.'" John 8:12, Jesus said, "I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life." Christ is the true path and light.
