Japan’s biggest law firm, Nishimura & Asahi was established in 1966 and has been involved in a number of arbitrations over the years, spanning M&A, joint ventures and construction. With Japan only recently beginning to make progress as an arbitral seat, the firm’s activities in this field have not been as visible as those of its counterparts in, for example, South Korea.

But the work is there. It has been active in disputes across Asia, taking on cases at major institutions like the ICC, SIAC and CIETAC, as well as the Japan Commercial Arbitration Association (JCAA), the Korean Commercial Arbitration Board (KCAB) and other recognised bodies in Indonesia, Vietnam and Thailand.

In 2010, it caught attention for winning a pro-New York Convention ruling in the Tokyo courts for insurance company AIU during set-aside proceedings; the case was shortlisted for a GAR award.

The practice is led by Tokyo partner Hiroyuki Tezuka, who is a familiar face around the region. He sits on the SIAC Court and the KCAB International Arbitration Committee, as well as the ICC Court.

The team in Tokyo includes partners Chie Nakahara and Lars Markert, a German and Swiss-qualified lawyer who joined from Gleiss Lutz in 2018, having previously spent two years on secondment at Nishimura & Asahi. He has experience in commercial and investment arbitration and sits as arbitrator.

In Singapore, partner Shintaro Uno has been helping the firm branch out into South East Asian arbitrations, particularly construction-related cases. That office is also home to counsel Natalie Yap, an English-qualified foreign attorney who joined in 2017 from Watson Farley & Williams.

The firm raised its international profile further in 2018 when it hired two new foreign attorneys, including Anne-Marie Doernenburg, a German national who previously practised at Freshfields Bruckhaus Deringer and is the Asia chair for the Institute for Transnational Arbitration.

Markert has been pitching for more investment arbitration work.


The firm has offices in four Japanese cities and 14 overseas offices in Beijing, Shanghai, Hanoi, Ho Chi Minh City, Yangon, Bangkok, Singapore, Taipei, Frankfurt, Düsseldorf, Dubai and New York, as well as affiliate offices in Kuala Lumpur and Jakarta. 

In 2020, Nishimura & Asahi became the first Japanese law firm to launch a formal law alliance in Singapore, after it teamed up with local firm Bayfront Law.

Who uses it?

Major clients have included Panasonic, Sharp, Toshiba, AIG, Novartis, Mitsubishi Fuso Truck and Bus, Mitsubishi Electric and Honda Motors.

Track record

A Japanese automotive company used the firm to good effect in a US$300 million dispute with a former Asian distributor. The firm obtained an anti-suit injunction in 2017 from a JCAA tribunal, then went on to prevail in the arbitration in the following year. The client was granted the declaratory relief it asked for along with costs.

In 2018, the firm successfully defended a Japanese automotive client in a US$70 million JCAA case brought by a former distributor in the Middle East. Herbert Smith Freehills in Tokyo was on the other side.

Together with a UK firm, Nishimura & Asahi helped a large Japanese corporation secure the dismissal of a US$175 million claim relating to the termination of a distribution agreement.

A team led by Uno secured a win for a Japanese client in a BANI arbitration, following which the respondent, a local developer, filed set-aside proceedings in an Indonesian court. 

Recent events

The firm obtained a favourable settlement for a Japanese client in a US$7.3 billion dispute over a joint venture between companies engaged in power plant construction projects in South Africa. This case, which the firm says is the largest arbitration in the history of the JCAA, saw the client receive a monetary payment and delivery of all shares in the joint venture.

Punjaporn Kosolkitiwong joined the firm from Dej-Udom & Associates as head of disputes in Bangkok.
