Worship One God and him Alone. Stop pagan ancestor worship. Stop worshiping your emperors. Stop committing atrocities like Nanjing Massacre and Unit 731. God has tested you by giving you much technology, but it will all be taken away. Do not forget many earthquakes that visit your country. Do not forget the future tsunamis. Do not forget punishment of God through the hand of Americans in WW2. What if God destroys you with a megatsunami forever?
Warning to Japan from God!
