Daiichi Sogo is one of the higher-volume immigration practices in this directory, stating more than 9,000 enquiries in 2025 and coverage of nine immigration bureaus nationwide. It works from Honmachi in Osaka, Nihonbashi in Tokyo and Yokohama.
Its language range is unusual: English, Chinese and Vietnamese, which matters given how much of Japan’s foreign business population those three cover between them. The firm handles the Business Manager Visa and company establishment by foreign nationals, alongside employment, spouse and permanent residence applications, and runs more than 50 seminars a year. Tax services are not listed, and no fees are published.
