Japan’s startup funding market held steady in 2025, but the underlying numbers point to a more selective investment environment. According to the “Japan Startup Finance 2025” report released by Speeda, total startup fundraising excluding debt reached 761.3 billion yen, nearly unchanged from 779.3 billion yen a year earlier. However, the number of companies raising capital fell 6% to 2,700, while the median funding amount dropped from 77.6 million yen to 62.4 million yen. The average raise remained flat at 310 million yen, indicating that a smaller number of large deals continued to support overall market totals.

The funding distribution became increasingly polarized. Companies raising less than 10 million yen increased to 448, up by 98 year-on-year, while the number of startups raising between 10 million yen and 50 million yen declined by 115. At the higher end, companies raising between 500 million yen and 1 billion yen rose slightly to 176, while firms raising more than 5 billion yen represented only a small number of deals but accounted for roughly 20% of all capital raised. Series A financing declined from 168.4 billion yen to 139.1 billion yen, while Series B funding increased to 192.4 billion yen despite a drop in the number of funded companies, highlighting a market where investors concentrated larger sums into fewer startups.

Large-scale funding increasingly flowed toward industry-focused and infrastructure-oriented startups. Robotics company Mujin recorded the largest fundraising round of the year, backed by the NTT Group and the Qatar Investment Authority. Space startup Interstellar Technologies raised 20.1 billion yen in Series F financing, including loans, while mobility ventures such as SkyDrive and autonomous driving firms Turing and T2 also attracted significant investment. AI startup Sakana AI announced a Series B round totaling approximately 20 billion yen, although the deal was not fully reflected in registry-based rankings at the time of calculation.

Investor composition also shifted during the year. Venture capital investment declined by 8% to 297.3 billion yen, while corporate investment increased by 32 billion yen to 148 billion yen. Financial institutions also expanded investment from 31 billion yen to 36.7 billion yen. In funding rounds exceeding 1 billion yen, corporations played a larger role as strategic investors, replacing some of the dominance previously held by venture capital firms. Meanwhile, 150 startup funds were established in 2025 with a combined size of 474.7 billion yen, surpassing the previous year’s total. Yet nearly 45% of those funds disclosed no size, while the median known fund size fell from 4 billion yen to 3 billion yen, suggesting a growing reliance on a limited number of mega-funds.

Exit activity also reflected a changing market. Startup IPOs fell from 133 in 2024 to 108 in 2025, with only 31 startup listings — the lowest level in a decade. The median initial market capitalization for startup IPOs rose from 8.9 billion yen to 13.5 billion yen as listing standards tightened and investors favored larger, more profitable businesses. At the same time, M&A activity remained elevated, reaching 167 acquisitions and subsidiary deals. One of the year’s largest transactions saw Mizuho Bank acquire a 70% stake in fintech startup UPSIDER Holdings for 46 billion yen. The data suggests that while capital remains available in Japan’s startup ecosystem, funding in 2025 increasingly favored companies with clearer growth paths, strategic value, or the scale to survive longer private-market timelines.
