After the 1960's, especially, a lot of fishing port facilities were constructed at the high economic growth period. Facilities maintained at this time have already exceeded 30 years, the future, it is expected that maintenance and renewal of facilities increase by decrepitude. The fishing port is an important infrastructure to supply fishery products, appropriate maintenance and renewal of the fishing port facilities are important policy because it supplies fishery products with stability. Then, we totaled the construction year and the amount of construction of outlying facilities and berthing facilities in the fishing port in Japan. Next, the cost of the renewal in the future was calculated by the amount of construction and the construction year. Finally, we clarified the point of problem of maintenance and renewal in the future. This result is as follows; the renewal of outlying facilities and berthing facilities increases from about 2000 and becomes a peak in around 2030. The renewal cost that exceeds 50 billion yen is needed in the seventeen prefectures. The renewal cost of twenty-four prefecture is higher than the budget in fiscal year 2009. Therefore, the renewal cannot be constructed by the budget in fiscal year 2009. In addition, the renewal cost of twelve prefectures becomes twice or more the budget in fiscal year 2009.
