Yonemori International Law Office


Since registered as an attorney in 1999, I have been satisfying needs of the clients, in various areas of business-related laws at a law firm reputed in international practice and a company listed on the first section of the Tokyo Stock Exchange.

Taking advantage of this experience, I, expeditiously and at a reasonable cost, offer services meeting needs of clients, ranging from specialized services for a large corporation to daily services for a small or medium-sized enterprise and an entrepreneurial venture.

In providing services, I commit to my cause that an attorney must be an “all-purpose problem solver,” someone who not only offers a legal opinion on but also brings a final resolution to a client’s problem, by exploring whatever way. In practice, I, for a single purpose of realizing a client’s business goal, support the client in such matters as investigating facts, creating plan B and coordinating among the interests of the stakeholders inside and outside the client, as well as in analyzing legal issues.

I appreciate your continued patronage.
