Since 2017, Japan has rapidly developed its hard and soft infrastructure to accelerate the use of alternative dispute resolution (ADR) in Japan, such as establishing the Japan International Dispute Resolution Center and the Japan International Mediation Center, Kyoto, as well as amending the Foreign Lawyers Act. The legislative process to amend the Japanese Arbitration Act is underway and discussions to accede to the Singapore Convention are ongoing. Mediation and settlement discussions involving judges during the litigation process are traditionally common in Japanese court practices, which would have some implications for investor–state mediation, which is a recent hot topic in the field of investor–state dispute settlement. Numerous means of further improving the efficiency and effectiveness of ADR proceedings have been discussed globally, including mid-stream conferences, Calderbank offers, the use of mediation in complex disputes, and the advanced use of Arb-Med-Arb proceedings utilizing party-appointed arbitrators.

2017年以来，日本快速发展软硬基础设施，加速替代性争议解决（ADR）在日本的运用，如设立日本国际争议解决中心、京都日本国际调解中心、修订《外国仲裁法》等。律师法。修订《日本仲裁法》的立法程序正在进行中，加入《新加坡公约》的讨论也在进行中。在日本法院实践中，诉讼过程中涉及法官的调解和和解讨论传统上很常见，这对近期投资者与国家争端解决领域的热门话题投资者与国家调解产生了一些影响。全球范围内讨论了进一步提高 ADR 程序效率和有效性的多种方法，包括中流会议、Calderbank 提议、在复杂争议中使用调解以及利用当事人指定仲裁员的 Arb-Med-Arb 程序的高级使用。
