Japanese aid has been continuously criticized as its modalities are focused on economic infrastructure via loans. However, support for economic growth and infrastructure has become more important due to the growing influence of recipient needs and emerging donors. Accordingly, Japan’s perception and implementation of its aid in the changing international regime in the 2010s are a salient factor. This study clarifies the common and different features between the official development assistance before the 1990s and the 2010s to identify which characteristics “returned” from the “Japan model” in the past. The domestic background and factors were examined to explain the alteration concentrated on the meaning of aid in the Abe administration’s policy directions and domestic actors. The results indicate the aid modalities in the 2010s are similar to the aid in the 1980s in some aspects, putting emphasis on economic growth, infrastructure, and cooperation with private sectors. But “quality growth” came into the slogan in the 2010s, as Japan is not the largest donor anymore. The Prime minister’s office (Kantei) led the aid policy as a part of priority policy “Abenomics” to support the prime minister in the 2010s, while collaborations among Liberal Democratic Party members, bureaucrats, and private actors led the aid policy in the 1980s.

日本的援助一直受到批评，因为其方式侧重于通过贷款提供经济基础设施。然而，由于受援国需求和新兴捐助者的影响越来越大，对经济增长和基础设施的支持变得更加重要。因此，日本对 2010 年代不断变化的国际制度的援助的看法和实施是一个显着因素。本研究阐明了 1990 年代之前和 2010 年代官方发展援助之间的共同和不同特征，以确定哪些特征从过去的“日本模式”中“回归”。考察了国内背景和因素，以解释这一变化集中在安倍政府政策方向和国内行为者中援助的含义。结果表明，2010 年代的援助方式在某些方面与 1980 年代的援助相似，侧重于经济增长、基础设施建设以及与私营部门的合作。但“质量增长”在 2010 年代成为口号，因为日本不再是最大的捐助国。总理府（Kantei ) 在 2010 年代作为优先政策“安倍经济学”的一部分领导了援助政策，以支持首相，而自民党成员、官僚和私人参与者之间的合作则在 1980 年代主导了援助政策。
