Working with Attorney Yoshiko Koizumi on our corporate merger was a highly professional experience. Her expertise in Mergers and Acquisitions Law was evident from the start, as she navigated complex regulatory hurdles with precision and clarity. The attention to compliance details, especially in corporate governance, was impressive, and we felt confident in her strategic approach. She is clearly recognized for a reason in the legal community. While her knowledge of antitrust law proved invaluable in structuring the deal, we did find her response times to be a bit slower than expected, particularly during the final stages. The cost of her services, while justified by her expertise, was also on the higher side for our budget. Despite these minor drawbacks, Yoshiko's ability to anticipate legal risks and her meticulous preparation made a significant impact on the outcome. For businesses needing top-tier corporate legal support, she is an excellent choice, just be prepared for a more measured communication pace.
