The purpose of my paper is ,firstly to clear the vague issues of WTO rules, for example, Article XXIV and Non Trade Concerns (NTCs) of Agricultural Agreement in WTO, and secondly to find a way out of the present Japanese agricultural difficulties through fulfilling four conditions, which are possibly satisfied not through WTO negotiation, but through FTA/EPA negotiations.Japan should negotiate with other countries, which have the same agricultural interests as Japan, and should focus on the FTA, which is WTO rule consistent. Japan should progressively make agricultural subsidy more WTO rule-oriented based on the preamble of WTO and Article XX of Agriculture Agreement.
