Korenari Kai in giving his legal opinion draws on his extensive experience of staying overseas as a diplomat, in environments of cultural and ethnic diversity. He has advised foreign clients primarily on employment laws, family law and immigration matters. He participated as a speaker on transnational estate planning in the 2006 New York State Bar Association meeting in Shanghai. He is also a writer of an article on animation films from the perspective of copyright law.

He is independent, not belonging to any large law firm, but has a high-quality network of able practitioners. He will where necessary tap into this specialist network, including top tax lawyers, cultivated during his diplomatic life and later on. On the strength of the network, he gives scrupulous, bespoke legal opinion of his own. What sets him apart from other English-speaking Japanese lawyers is his straight-forward, articulate opinion intelligible to non-Japanese clients. His opinion sometimes includes not simply strict legal view but strategic/cultural advice as well. His experience in cultural/ethnic diversity helps in this undoubtedly.

He works exclusively in civil matters. He is willing to take up litigation on behalf of overseas clients. He is perfectly at home in English.

Trying the service of an internationally-minded and independent lawyer like Korenari Kai is a viable alternative, particularly when it comes to personal matters and litigation, to engaging large Japanese law firms.
