Reasons why fishing is more developed in Japan than in Kenya

Japan is made up of islands hence they have a long fishing tradition which has made them develop efficient fishing technology whole Kenya is the mainland with little sea tradition

Japan is mountainous with thin permafrost soil which inhibits agriculture, so the Japanese have turned to fishing as the main occupation while Kenya is an agriculturally oriented population hence little attention to fishing.
Japanese have done extensive research on fishing while Kenya has little research on fishing.
Japan’s large population provides a ready market for fish while Kenya has relatively few people who eat fish.
Japan use well-developed and advanced fishing methods, vessels and fleets while Kenya use traditional fishing methods and vessels e.g. canoes.
Japan has an indented coastline with many natural harbors while Kenya has a regular coastline and hence has poor fishing ports and villages.
Japan has an extensive continental shelf which is shallow coupled with cold and warm ocean currents hence rich in plankton that attract abundant fish while Kenya has a narrow continental shelf resulting in few planktons to attract abundant fish.
Japan is equipped with strong fishing vessels that can verger into deep off Shore Sea fishing while Kenya can only operate a few kilometers off the shore.
