This paper aims to systematize the diversity of irrigation modernization through comprehensive review of present prospects and surroundings about the modernization. Focusing on saving water, it was clarified that general movement of the modernization was subject to the strategic concept concerning integrated water management presided by the water sector. Moreover, 'spontaneity-based approach' in which irrigation water demand is reduced by means of motivating water users internally, is superior rather than 'regulation-based approach' in which the demand is controlled by regulation and restriction externally. In this respect, the agricultural sector should take the lead in a promotion of the demand management putting her advantages for adopting the former approach. Furthermore, analysis reviewed several modernization projects was indicated that irrigation modernization could be simplified into four categories, namely, 1) improving irrigation water delivery and use service to users, 2) raising management level in quantify of water, 3) raising management level in quality of water, 4) reducing governmental intervention in operation and maintenance.
