Practice Experience<\/h3><\/div>

Anthony Luna advises on corporate and commercial matters, with a focus on (i) cross-border M&A, (i) venture capital transactions, and (iii) technology law, and AI governance. He has experience in technology and data-driven matters and maintains a strong interest in emerging fields such as AI, quantum computing, semiconductors, and space as part of his practice.<\/p>\n

He brings a dual perspective uncommon in the Japanese legal market, having served both as an M&A partner at a top-tier international firm and as an award-winning General Counsel and senior executive at a major global technology company.<\/p>\n

Anthony began his legal career in California before relocating to Japan, where he practiced with a major international law firm in Silicon Valley and Tokyo, representing emerging-growth companies, venture investors, and multinational corporations in cross-border acquisitions, joint ventures, strategic alliances, and commercial transactions. He also completed a secondment to Itochu Corporation\u2019s Legal Department, supporting international projects and investments across multiple jurisdictions.<\/p>\n

He later joined Jones Day\u2019s Tokyo office, where he served as a partner in the corporate and M&A group and advised Japanese and international MNC\u2019s on global transactions and strategic matters.<\/p>\n

Immediately before joining southgate, Anthony served as Senior Operating Officer, Board Member, and General Counsel of IBM Japan, Ltd., overseeing all legal, IP, regulatory, and security functions and leading a department of approximately 45 legal professionals. He handled significant litigation, restructuring, cybersecurity incidents, and high-value technology transactions and served as sponsor executive for IBM Japan\u2019s AI Ethics Team.<\/p>\n

Anthony is an adjunct professor at Keio University Law School, where he teaches courses on AI and legal trends and startup and venture law.<\/p>\n<\/div>
