Japanese investment in Indonesia remains meaningful in 2026, and the official flow numbers underline that the relationship is not retreating. In the first half of 2026, Japan was Indonesia’s fourth-largest source of foreign direct investment, realizing US$1.9 billion, which BKPM said represented 6.2% of total incoming FDI for the period. This sits inside a broader capital picture where FDI contributed Rp507.6 trillion (US$31.72 billion), while domestic direct investment added Rp502.9 trillion (US$31.43 billion). At the same time, the narrative is shifting: the partnership is increasingly framed around economic security, with energy security described as a central pillar of Japan’s cooperation with Southeast Asia, alongside alignment on investment that supports energy security and the energy transition.
The auto sector still matters, but it no longer tells the whole story—and it is also where the pressure is easiest to quantify. In Indonesia’s passenger vehicle market, Japanese brands held 89.5% share in 2024, down from 91.7% in 2023, while Chinese brands rose from 3.2% to 6.4% over the same period. Gaikindo data cited in reporting also put 2024 vehicle sales at over 865,000 units. The 2025 market picture looked harsher for legacy leaders: one analysis of Gaikindo full-year 2025 statistics described a second consecutive year of contraction, domestic production down 4.1%, and imports of finished vehicles up 82.0%, with a December record of 94,100 units tied to the end of a tax incentive system for imported BEVs.
Beyond Cars: Energy Security, Green Industry, and Export-Linked Bets
What “beyond autos” looks like in practice is a broader investment agenda that blends energy transition themes with Indonesia’s downstream push. After Indonesia’s participation in the 2025 World Expo in Osaka, ANTARA reported potential investment commitments estimated at US$28.9 billion, including US$22.3 billion pledged directly to green industries and downstream sector developments. This matters for how Japanese firms weigh long-term positioning. A JETRO survey on business conditions in Asia and Oceania, covering more than 1,600 companies for Indonesia, found a mix of optimism and concern, while still highlighting Indonesia’s market size and growth potential as key attractions, supported by relatively competitive labor costs and the ease of working with local talent.
Manufacturing, however, is not disappearing—it is being re-anchored to new production and export dynamics. Worldmetrics reported that total investment in EV production in Indonesia reached IDR 30 trillion (USD 2.1 billion) in 2023, and that Indonesia produced 1.3 million light vehicles that year. On exports, the same source stated Indonesia exported 500,000 vehicles in 2023, with export revenue from automotive products at IDR 250 trillion (USD 17.5 billion), and EV exports reaching 10,000 units (mostly EV two-wheelers). More recent export snapshots still show Japanese strength in outbound flows: one export-market report said three Japanese brands shipped 39,859 of 47,560 complete built up units exported in May 2026, or 83.81%.
The implication is that Japan Inc. can be challenged in showroom share while still staying central to Indonesia’s industrial and investment story. Competitive disruption in 2024–2025 is real, with finished-vehicle imports surging and Chinese brands taking share, but the response is not only about selling more cars. It is also about where capital is pointed: toward energy security cooperation, green industry and downstream commitments associated with the Osaka Expo pipeline, and production models that link Indonesia to export markets. For Japanese firms assessing where to deploy capital next, the signal is a diversification of priorities rather than a simple exit from Indonesian manufacturing.
