Objectives During the 3/11, approximately 19,000 lives were taken, and even though it took roughly 40 minutes after the earthquake stopped for the tsunami to arrive, most of the inhabitants were at loss as to where they should go. Now, 6 years have passed since the 3/11 and the number of tsunami evacuation buildings that fulfill the requirements of the state as a refuge in case of emergency have increased in number more than 7 times, but nobody tries to know and want to check these places. The probability of a strong earthquake occurring in areas along the Nankai Trough within 30 years has risen by 1 to 2 percentage points, a new report has found in 2016. In order for people to know the meaning of the places, we made orange flags.

In the Pacific coastal regions of Japan, tsunami disasters by the Nankai Trough Mega Earthquake are anticipated. The #beORANGE hold events in an effort to raise approximately 100 orange flags along the coastal town or coastlines. (These were located on tsunami evacuation buildings, schools or apartments. All terms and locations were based on the hazard map of each region.) Start: July 18: Marine Day End: World Tsunami Awareness Day At October 23rd, we delivered the extras to inhabitants with 49 tsunami evacuation buildings orange. In advance, all building owner of the region agreed and started to raise flags in the morning. During activities, we issued a convenient wristband. It has over 10 uses and can hold over 200kg among other functions.
