Atsumi & Sakai's client roster includes global investment banks, major real estate developers, J-REITs and asset managers. The group is particularly strong in structured finance and securitisation transactions but covers the full spectrum of real estate transactions and development mandates. Russell Kawahara – who jointly leads the team alongside Miho Niunoya – recently represented a private fund in the sale of six high-class office buildings in Japan, and acted for a foreign fund in its acquisition of a portfolio of Japanese logistics facilities. A team including Shuji Koyama assisted a private company as part of a consortium with the outsourcing of the entire operations of a sewage system as part of a new PPP model, which includes the construction and maintenance of new facilities. The group also collaborated with the projects and energy department's Miki Ono to oversee the localisation of a foreign standard form construction contract related to the construction of several projects in Japan. Also noteworthy is Eiichiro Hata who specialises in the banking and financing aspects of the practice.
