構造のものであった。In addition, in recent years, rock fishing has become explosively popular as an easy and healthy form of recreation, and artificial rock fishing spots have been set up in urban areas where fishing spots are not readily available. However, the structure of conventional artificial rock fishing areas is mainly made of iron pipes or steel frames. Examples include piers for sea fishing parks, etc. In either case, the appearance does not match the natural landscape, and in addition, fishing from a far distance from the water surface, and fishing from the shore while being in direct contact with seawater etc. The structure made it impossible to enjoy play.
