Jurisdiction overview

Japan has a robust independent legal market dominated by a handful of local brands. Attorneys at law – known as bengoshi – form the backbone of the country's legal community, while gaiben are lawyers from foreign countries licensed to practice law in Japan. A third category denotes foreign lawyers qualified under Japanese law. 

The liberalisation of Japan’s legal sector has been a gradual process, and before the introduction of the 1987 foreign lawyer law, the market had been completely closed to foreigners for 32 years. In 1994 an initiative that allowed bengoshi and gaiben to form specific joint enterprises and share profits didn’t attract much attention due to restrictive conditions and it wasn’t until 2005 that Japan began to see a notable increase in the presence of foreign lawyers. 

In 2005 gaiben were allowed to enter full partnerships with Japanese firms, which significantly eased restrictions on partnerships’ areas of practice. Although still only allowing Japanese lawyers to practice Japanese domestic law, a foreign lawyer qualified under Japanese law and gaiben were allowed to hire bengoshi and share a unified name. In 2010 amendments allowed foreign firms to incorporate as a Law Corporation allowing them to operate from their own offices in Japan. Firms operating in partnership with a domestic Japanese bengoshi lawyer were also permitted to form Law Corporations.

The international law firm response to these developments was diverse. A number took advantage of this liberalisation to provide a more comprehensive service to their clients, while others chose not to fully merge with Japanese law firms - remaining in joint venture arrangements with Japanese firms or individual bengoshi. Other international law firms with a presence in Japan decided to remain independent.

Despite painstaking liberalisation, it’s clear that over time increasing pressure alongside socio-economic realities of globalisation are combining to supplant protectionist concerns. 

In regards to firms themselves, the 'Big Four' – namely Anderson Mōri & Tomotsune, Mori Hamada & Matsumoto, Nagashima Ohno & Tsunematsu and Nishimura & Asahi – is an informal term denoting the largest firms headquartered in Japan. More recently, the moniker 'Big Five' has become increasingly used to accommodate TMI Associates, which has grown rapidly since its establishment.

IFLR1000 2019: Japan market trends and developments

Financial and corporate
Anderson Mori & Tomotsune

As one of Japan’s Big Four (四大) Anderson Mori & Tomotsune (AM&T) is strong across the board, particularly in banking, finance, and capital markets work where it has a strong reputation in the primary offerings of Samurai bonds, Uridashi offerings, J-Reits, equity offerings, and international offerings of convertible bonds by Japanese issuers.

For example, in the research period the firm advised Ezaki Glico in its issue of ¥30 billion zero coupon convertible bonds due 2024, and acted for Canadian Solar Infrastructure Fund in its global IPO, which was the first global offering of an infrastructure fund listed on the infrastructure fund market of the Tokyo Stock Exchange.

In M&A the firm has been active in the consumer electronics sector advising KM Holdings, an SPC established by a fund managed by MBK Partners, in its acquisition of Kuroda Electric; and acting for Japan Industrial Partners alongside KKR in its agreement with Hitachi for the take-private of Hitachi Kokusai Electric.

The airport sector has been hot in recent years in Japan and AM&T’s projects team advised Kobe city in the sale of a concession right to operate Kobe Airport to a consortium made up of Orix Corporation and Vinci Airports.

Key clients of the firm include Vedanta Group, Sumitomo Forestry, Obayashi Corporation, Shinsei Bank, The Bank of Tokyo-Mitsubishi UFJ, and Goldman Sachs Japan.

Client feedback

“Its service is very prompt and 98% of the time delivers within the timeframe agreed. I’m impressed with its speed of turnaround for some of the matters that it has handled for us.    Overall, my experience has been positive.” - Banking

“Capable and time-sensitive.  Good service.  Through long relationships it knows our company's situation and gives the right advice.” - Banking

“The go-to law firm in the India-Japan corridor.” - M&A   

“In any given year, I engage and work with about 90 different law firms from about 70 countries seeking advice on a number of projects for my financial institution clients.  In my mind, Anderson Mori stands out not only in Japan, but worldwide, for the quality and the outstanding training of its lawyers that enables it to deal with complex cross-border legal issues and cultures.  Japanese legal practice presents a lot of complexities.  It is critical, therefore, to work with a firm that understands how to translate Japanese concepts into terms that are familiar to practitioners from civil and common law countries alike.  However, the ability to explain is not all.  In complex cross-border matters, a client needs a law firm that is deeply proficient in the subject matter, as well.  Anderson Mori is such a law firm.  In my experience, the firm has consistently provided outstanding services, often times beyond expectations, in complex cross-border insolvency, financing, and bank regulatory matters.  The firm particularly benefited from the 2015 combination with most of Hideyuki Sakai's restructuring and finance team originally at Bingham Sakai.” - Restructuring and insolvency

Yuri Ide

“Yuri Ide is deeply proficient in insolvency and finance matters. In particular, it is difficult to find in Japan another lawyer with her experience and versatility in cross-border insolvency. She is incredibly responsive and very clear in her analysis of the issues. Yuri is also very strategic and hugely helpful in analysing all credit and insolvency risk angles, and in suggesting legally viable and at the same time practical solutions.  I can't identify any weaknesses in her practice.  She is and will continue to be my go-to person at a firm that lists so many other eminent lawyers."

Atsutoshi Maeda

“Maeda-san is able to explain differences between aspects of Japanese law and common law, and what market practice is in Japan; this helps me a great deal in understanding contract provisions with our Japanese customers, and also standard commercial and dispute practices in Japan. I am pleased with the high standard and quality of advice and work he and his team have delivered."

"Excellent. He is helpful and knowledgeable." 

"He's a good communicator with international acumen who provides practical solutions to issues."

Yoshihito Shibata

"He has expertise in the M&A and insolvency area."

 Ryu Umezu

“Ryu Umezu is an excellent lawyer.”

"Competitive price, reliable for assistance, good responsiveness and global capability." – Capital markets

"They are very responsive, and their advice is always practical while logical.  The weakness is that I sometimes feel that they don't have strong governmental connections in Japan as compared to local big firms." – M&A, Capital markets, Banking and finance

"Clifford Chance is exceptional in terms of their global foot print and access to wide variety of legal expertise needed to close out the transactions.  It is particularly helpful when it comes to a situation where we require a one stop combined solution of each jurisdiction. Clifford Chance has global foot print and coverage where we invest in. At the same time, depth of expertise is excellent as well. To my knowledge, only handful of law firm are able offer.

"Because they have plenty of experience with finance and natural resources projects, we asked Clifford Chance to be our legal advisor in the Indonesian project.
