Among various meteorological and oceanographical elements, wind direction plays one of the most important roles in navigation. In the age of sailing, wind directions were generally referred to by their local names or "slanguages", and, even at present, fishing boats which operate at inshore or coastal seas frequently use them. But, in fact, accurate directions of winds in such local names are in most cases rather ambiguous, and same names in different regions of the country are often used to denote entirely different directions from each other. The slanguage "Narai" is used widely along the eastern coast of Honsyu, and its direction varies from SW to E clockwise gradually from northern to southern districts. Taking meteorological data into account, the characters of Narai are classified as follows, A. Sanriku to Kanto District: SW-N, seasonal westerly prevailing wind in winter, B. Southern Part of Kanto to Izu Islands: N-NE, April to November, most frequent in October and November, C. Izu Peninsula to Eastern Coast of Kii Peninsula: NE-E, April to November. This slanguage seems to have been originated in A-region, and to have been carried to C-region, mostly through B-region by fishermen or navigators. Several other slanguages that have not been recorded heretofore in folk-lore of Japan are newly found.
