Brave Japanese captains defy nature to save their ships in the harbor. Here is the follow-up www.youtube.com/watch?v=qpI4qfa12Zs with one of the captains where he says:"I felt it's only required to cross over just single big wave. Fear brings you nothing, so I said to myself there's no fear and run at full throttle. The ship fell about 5 meters low after once mounting on the wave. Then I swirled it in zigzag, watching the flow and for anything coming off the coast."
