Based on the results of the previous study on Itsukushima Shrine, we focused on the “corridor” and examined the floorboards of the corridor as a measure to mitigate the effects of waves and storm surges based on the sea conditions. The floorboards of the corridor are expected to reduce the energy of short-period transmitted waves toward the main hall. However, it is difficult to adopt the idea that the corridor was screened to reduce the wave energy.
