昭和南海地震（1946年）の津波到達の標柱です。山の斜面には津波の到達水位（約7.9ｍ）が示されています。袋付近は津波が高くなる地形的特長があり、次の南海トラフでの巨大地震で想定される浸水深は周辺地域より大きくなっています。

It is a pillar of the arrival of the tsunami of the 1946 Showa Nankai earthquake. The reaching water level of the tsunami (about 7.9m) is shown on the slope of the mountain. The area around the bag has a topographical feature that the tsunami becomes high, and the inundation depth expected by the next huge earthquake in the Nankai Trough is larger than that in the surrounding area.
