Power of Attorney for Haruyuki Yoshikawa

This filing is an Exhibit 24, a Power of Attorney granted by Haruyuki Yoshikawa to several individuals, including Kenji Miyaki, Keita Shirakuma, and Masahiro Hokura. The purpose of this Power of Attorney is to authorize these individuals to act as Yoshikawa's representatives in all matters related to filing documents with the SEC. This includes obtaining and maintaining EDGAR system credentials, executing and filing Forms 3, 4, and 5 (and any amendments) as required by Section 16 of the Exchange Act, and preparing and filing Form 144 for potential sales of company stock. The attorneys-in-fact are also empowered to manage Yoshikawa's EDGAR account, including appointing other administrators and ensuring account security. This Power of Attorney remains in effect until Yoshikawa is no longer required to file these forms or until it is revoked in writing. It supersedes all previous powers of attorney for this subject matter.
