Abstract: In this study, the site survey on the structural characteristic of stairs at the entrances to the underground mall in the JR Hakata Station has been executed. The obtained results are able to propose not only qualitative aspects but also quantitative ones. In particular, it is realized that the stairs in the JR Hakata Station are fallen into four categories (straight stair [2 blocks], straight stair [3 blocks], bending stair and turning stair) and that the mean slope gradient of stairs in the JR Hakata Station is equal to 25 degrees. It is also obvious that the raito of setting a footstep on the ground level's entrance is 44%.
