On December 31, 2025, Brazil and Japan mark the 58th anniversary of the entry into force of the Agreement for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion. This agreement was signed on January 24, 1967, and later supplemented by an additional protocol signed in 1976 and in force since 1978.
The agreement defines the taxes covered, applying to the federal income tax in Brazil and to the income tax and corporate tax in Japan.
Regarding diplomatic relations between the two countries, they were established in 1895 through the Treaty of Friendship, Commerce and Navigation, which enabled the reciprocal opening of diplomatic representations in 1897 and encouraged Japanese immigration to Brazil beginning in 1908.
