On Tuesday, Japan and Brazil announced that Tokyo will launch negotiations on an economic partnership agreement (EPA) with Mercosur by the end of the month. The decision was made during a meeting in Evian‑les‑Bains, France, on the sidelines of the three‑day Group of Seven (G7) summit.

Prime Minister Sanae Takaichi and President Luiz Inácio Lula confirmed the launch of the talks, saying the agreement would broaden Japan’s access to Mercosur markets and diversify supplies of critical minerals. The move comes after China tightened restrictions on rare‑earth exports, prompting Japan to seek alternative sources.

Mercosur, the South American trading bloc that includes Argentina, Bolivia, Brazil, Paraguay and Uruguay, represents a market of roughly 300 million people and a combined GDP of about $3 trillion, according to Deputy Chief Cabinet Secretary Kei Sato. Sato added that the bloc is rich in resources such as critical minerals, energy and agricultural commodities, and that Brazil’s status as the largest economy in the group and a major oil producer makes it a key partner.

Japan’s interest is largely focused on automotive exports and other manufactured goods. The EPA would potentially lower tariffs on Japanese cars and parts, while also opening Mercosur markets for Japanese technology and services. At the same time, the agreement is expected to secure a steadier flow of minerals like lithium, nickel and rare earths that are essential for Japan’s high‑tech and electric‑vehicle industries.

Some lawmakers in the ruling Liberal Democratic Party (LDP) have expressed caution. They warn that increased imports of beef and chicken from Mercosur could hurt domestic producers. The Japanese government said it would seek to protect sensitive agricultural sectors during the negotiations.

In a separate meeting, Takaichi met French President Emmanuel Macron to deepen cooperation on economic security, critical minerals and advanced technologies. The two leaders also discussed security challenges in the Indo‑Pacific, including China’s regional posture, North Korea’s denuclearization, and the abduction issue.

The announcement was made while Lula was attending the G7 summit as a guest of France. The G7 meeting, which ran from 15 to 17 June, focused on a range of global issues, but the Japan‑Mercosur partnership was a key agenda item for Tokyo.

The EPA negotiations are part of Japan’s broader strategy to secure supply chains and reduce dependence on any single country. The country has already signed 22 free‑trade agreements and is currently negotiating other deals, including a recent agreement with Bangladesh.

Mercosur’s own trade policy has evolved over decades. Established in 1991, the bloc has grown to become the fifth‑largest economy in the world. Its focus on free trade and customs union arrangements makes it an attractive partner for countries seeking to expand market access.

The next steps for the EPA will involve formalizing the negotiation timetable. According to reports, Japan will begin talks by the end of June, with the first round of negotiations expected to take place in Tokyo or a Mercosur member country. The agreement will then need to be approved by the respective parliaments before it can enter into force.

At present, no vote or legal deadline has been set. The Japanese government has indicated that it will monitor domestic industry concerns closely and will incorporate protective measures for sensitive sectors. The outcome of the negotiations will determine whether Japan can secure a more diversified supply of critical minerals and expand its export market in South America.

The partnership also signals Japan’s intent to strengthen ties with resource‑rich regions outside of Asia, a move that could reshape trade flows and geopolitical alignments in the coming years.

In summary, Japan and Brazil have agreed to start EPA negotiations with Mercosur by the end of June. The talks aim to open Japanese markets to Mercosur goods, secure critical minerals, and address domestic industry concerns. The next phase will involve formal negotiations and parliamentary approvals, with no definitive timeline yet announced.
