Following an extensive nomination process, Asia Business Law Journal unveils the top performers of Japan’s legal profession. Lim Miran and Nguyen Yen report
Since fully reopening last year, Japan’s economy has been experiencing moderate growth, strengthening the prospects for a long-term economic revival and expansion, and legal professionals are essential in helping Japanese companies soar at home and when venturing abroad.
Amid the headwinds created by a sluggish global economy and interest rate hikes in the US and Europe, Japanese companies are looking for growth overseas in Southeast Asia’s emerging markets, and in the US. The startup ecosystem is set to receive vigorous support from the Japanese government, which has pledged to increase annual startup investments to JPY10 trillion (USD69.5 billion) by 2027.
The country’s legal sector is also adapting to align with the evolving business landscape. In April, the parliament approved a landmark amendment to Japan’s Arbitration Act, marking the first major revision in two decades. Alongside this amendment, an implementing act for the Singapore Convention on Mediation was passed to enhance accessibility to Japanese courts for the enforcement of arbitration awards and settlement agreements resulting from mediation, fortifying the country’s alternative dispute resolution framework.
On finance stimulus, Japan’s tax reform package was unveiled in December 2022 and submitted to the parliament in February 2023, and encompasses measures designed to bolster the Japanese startup ecosystem. The government also plans to establish a strategic council dedicated to exploring the application and regulation of artificial intelligence (AI) in light of the rapid advancements in generative AI technology.
Against this challenging yet exciting backdrop, we present our annual A-List of the top 100 lawyers practising in Japan – including foreign legal consultants, advisers and counsel. The A-List is based on extensive research conducted and nominations received from in-house counsel based in Japan and elsewhere, as well as Japan-focused partners at international law firms.
Nearly all of the A-List lawyers are strategically located in Tokyo, the epicentre of country’s legal and commercial activities.
Comments submitted to Asia Business Law Journal by clients suggest that they look for experienced lawyers who are not only well-versed in their respective fields but also demonstrate a client-centric approach, providing personalised attention and proactive guidance.
With extensive expertise and a deep understanding of the intricacies of business law, many lawyers in the A-List are recognised as businesses’ trusted guides in navigating the complexities of corporate transactions, financial regulations and compliance.
Akira Ehira, a partner at Mori Hamada & Matsumoto, is one of them. He is nominated by Yuka Ono, a partner at Brazilian law firm Pinheiro Neto Advogados in Sao Paulo.
“Akira Ehira has great expertise in the banking area. He is very client-oriented and assists clients to navigate through the complexity of financing and banking regulatory matters,” says Ono.
Ehira is also recommended by Hisashi Ishihara, finance manager at corporate credit card issuer Upsider in Tokyo. “Akira has a high understanding of our company at a management policy level. He is an essential partner whom we can rely on with peace of mind,” says Ishihara. “We received highly feasible advice for our negotiations that make the stakeholders understand our business intentions. As a result, we were always able to negotiate with confidence as a company.”
Efficient services and long-term solutions are mentioned by Ishihara as other essential elements contributing to Ehira’s success.
Ehira’s colleague, partner Katsumasa Suzuki, is praised by Takashi Unoki, senior manager of the legal department at electronic payment services developer PayPay in Tokyo.
“Katsumasa is a top-tier practitioner with particular expertise in the M&A transactions and capital markets sector,” says Unoki. “Having worked with Katsumasa and his team for several transactions, he and his team always support us with precise and useful advice. Although our requests are sometimes, or always, rushed, he and his team provide us with punctual, solution-oriented and insightful service, which is highly helpful to us.”
Keigo Kuroda, CEO at investment management solutions and real estate advisory services company Crosspath Advisors in Tokyo, recommends Baker McKenzie partner Seishi Ikeda for his outstanding performance and skill set.
“His exceptional legal skills in the real estate area that he focuses on are matched by his impressive work ethic and dedication to achieving the best possible outcomes for his clients,” says Kuroda. “In addition to his legal expertise, Ikeda is an excellent communicator who is able to explain complex legal concepts in a clear and concise manner. He is not only an outstanding lawyer, but also possesses a remarkable sense of business matching.”
Ikeda’s longstanding client for more than 10 years, Ashwin Wagh, vice president of finance at women’s apparel company Tillsonburg in Hong Kong, agrees.
“We are really fortunate to have Ikeda as our lawyer and adviser for all our group’s real estate investment matters in Japan,” says Wagh. “He is absolutely hands-on, with thorough knowledge of Japanese real estate dealings and tax matters, and under his guidance, has helped set up various holding and operating structures, and advised us on various complicated cross-border tax issues.”
For Ganesh Rao, a partner at Indian law firm Trilegal in Mumbai, King & Spalding partner Mark Davies is his go-to lawyer. “Mark is an excellent lawyer with significant knowledge commercially,” says Rao.
Gaurav Wahie, a partner at Indian law firm JSA in New Delhi, also speaks highly of Davies. “Mark’s experience and knowledge ensure that he is able to anticipate issues and provide focused advice,” says Wahie. “His advice and solutions, which are commercially oriented, pragmatic and legally strong, ensure that the client achieves the objectives and is legally protected”.
