While Japan remains a top-tier investor for Vietnam, recent government data reveals a stark 75% year-on-year decline in new Japanese investment pledges, which fell to $233 million in the first quarter.
Prime Minister Takaichi is expected to advocate for structural improvements in the Vietnamese business environment, specifically addressing grievances from Japanese multinationals regarding delayed payments for completed works and barriers to entry for large-scale infrastructure projects.
The investment relationship has faced recent hurdles, including Japan’s withdrawal from a major nuclear power project last year due to restrictive construction timelines. However, bilateral trade has demonstrated resilience, surging 12.3% in the first quarter to reach $13.7 billion.
In a potential move to ease corporate friction ahead of the visit, Hanoi recently announced it is reconsidering a proposed ban on petrol-powered motorcycles in its city center, a policy that has faced significant opposition from major Japanese manufacturer Honda.
Beyond economic negotiations, Takaichi’s itinerary includes meetings with Vietnamese counterpart Le Minh Hung and a scheduled address at Vietnam National University.
The speech is expected to focus on the evolution of Japan’s "Free and Open Indo-Pacific" strategy, emphasizing regional stability before the Prime Minister continues her tour to Australia.
The visit underscores Japan’s strategic intent to maintain its influence in Southeast Asian manufacturing hubs despite shifting capital trends.
