The Tonankai and Nankai earthquake is said to occur 80-90% of the probability in 50 years. Height of tsunami by the earthquake is predicted more than 1.5m in the Port of Osaka. If many ships evacuate at once, they will be in panic in Osaka Bay. Here the Hazard Chart of Tsunami in Osaka bay is proposed for vessel evacuation in safety. Mutual vessels' distances and distance to shore line are estimated around 2,000m. According to statistical data about 110 vessels exist in Osaka Bay a day, the surface area of Osaka Bay has enough to evacuate all of those vessels. Some ban areas and the emergency tracks are designed in the Hazard Evacuation Chart for the dangerous cargo and the large commercial ships, and the Chart is designed for the general cargo ships and the small boats, respectively.
