The quantity of accumulated litter on a beach indicates the pollution level, whereas the quantity of beached litter relates to the density of floating marine litter and the amount of inappropriate waste disposal. The purpose of investigating either accumulated litter or beached litter is to obtain the index quantity of litter for an entire beach, and to research the changes of quantity or the differences between other beaches. For this purpose, it is essential to investigate several representative items on a long beach area, with the exclusion of small debris. The reliabilities for the survey area and the measured value can be evaluated with an excess quantity, which is represented by the equation [100×(|Q1-­Q2|)/(Q1+Q2)] where QN is the quantity of litter on Site N. In order to reduce the influence of irregular data of survey areas, it is important to investigate several locations. Assuming that the excess quantity is about 10%, in order to obtain the reliable quantity of the beached litter on the beaches facing the Sea of Japan, it is nessary to investigate at least 500 m of beach-­line area of 6 beaches every month.
