近年来日印关系日益密切，双方高层互动频繁，两国首脑更是成功实现了年度互访。日本与印度深化合作关系有其深层次动因，包括：印度自身经济发展取得的瞩目成就，印度是陆海复合型国家、在印度洋沿岸拥有得天独厚的地缘战略优势，日印在成为“大国”的战略目标上有相互的战略需求与利益契合点。日印深化合作关系也面临着一些挑战，双边关系中存在着一些分歧。日印两国各自的外交传统与外交长远战略目标不尽相同，日印双方发展合作关系的出发点、双方自身国情的不同以及要达到的目标不尽相同，中国因素的存在对于日印关系而言也是一把“双刃剑”。未来日印关系会继续得到发展，但不会一帆风顺，其潜在的隐忧会在某个时候给双方关系的发展带来麻烦。
近年、日印関係はますます密接になり、両国間の高レベルの交流が盛んに行われ、両国の首脳は年に1回の相互訪問を行っている。日印協力関係の深化理由について、インドの経済発展の成果、インドの陸海複合型国家特性、インド洋沿いの独特な地縁戦略的優位、「大国」を目指すという日印共通の戦略目標などが挙げられる。一方、日印の協力関係にいくつかの課題が残されている。日印協力関係の出発点、両国の国情、最終目標なども異なっている。なお、中国の存在は日印関係にとっても「両刃の剣」となる。将来日印関係は引き続き発展していくが、必ずしも順調ではない。その潜在的な憂いは、いつか双方の関係発展に支障を来たしかねない。
In recent years，the relations between Japan and India have been closer with the development of high-level interaction. The prime ministers of Japan and India have achieved annual exchanges of visits. The strengthening of Japan-India cooperation is driven by various factors. India has gained remarkable achievement in its economic development. As a land-sea country，India has a unique geostrategic advantage on the Indian Ocean coast. Japan and India share common interest in pursuing their strategy of becoming a great power；However，there are still some obstacles and challenges in deepening the cooperation between Japan and India. Japan and India have different diplomatic traditions and strategic goals，and their starting points for developing cooperation between Japan and India are also different. The “China factor” serves as a “double-edged sword” for the relations between Japan and India. Japan-India relations will continue to develop in the future，meanwhile，there are still potential hidden contradictions that may cause setback for the cooperation between Japan and India.
