Japan has unveiled an ambitious long-term economic strategy that aims to reshape the country’s growth trajectory over the next decade and beyond, placing public investment at the centre of a plan designed to stimulate productivity, strengthen strategic industries and redefine fiscal policy. According to Nikkei Asia, Prime Minister Sanae Takaichi’s cabinet approved its annual economic and fiscal policy blueprint on Tuesday, outlining a framework that seeks sustained economic expansion through fiscal 2040 while introducing a new approach to managing government finances.
The policy document, known in Japanese as “Honebuto no hoshin”, presents what the government describes as “responsible and proactive public finances” for the period between fiscal 2027 and fiscal 2040. The blueprint signals a departure from previous fiscal priorities by placing greater emphasis on long-term investment designed to generate productivity gains rather than focusing primarily on short-term budget balances. Its release has already drawn close attention from financial markets, where investors are weighing whether the strategy can generate lasting economic growth without increasing concerns over government borrowing.
At the centre of the blueprint is a target to achieve sustained inflation-adjusted real gross domestic product growth of more than one per cent as early as possible while maintaining inflation around the Bank of Japan’s target of two per cent. By fiscal 2040, the government expects its strategy to help raise annual domestic private capital investment to 230 trillion yen and expand nominal GDP to almost 1,100 trillion yen, compared with 669 trillion yen projected for fiscal 2025.
The scale of those ambitions has prompted discussion among economists. Forecasts compiled by the Japan Center for Economic Research indicate average real GDP growth of 0.93 per cent in fiscal 2027 and 0.85 per cent in fiscal 2028, both below the government’s target. Nevertheless, Koji Takeuchi, senior economist at Itochu Research Institute, said achieving that level of growth would be a necessary condition for improving fiscal discipline, highlighting the connection the government is attempting to establish between stronger economic performance and longer-term fiscal sustainability.
The government’s investment strategy focuses on 17 priority sectors first identified in June, reflecting an effort to strengthen industries viewed as essential for future competitiveness and economic security. Artificial intelligence, semiconductors, biotechnology, defence, energy and shipbuilding are among the areas expected to receive significant attention as Japan seeks to encourage combined public and private investment totalling 370 trillion yen by fiscal 2040.
Artificial intelligence occupies a particularly prominent place within the blueprint. The government places special emphasis on what it describes as “physical artificial intelligence”, combining AI technologies with Japan’s long-established manufacturing capabilities in an effort to accelerate what it calls “AI transformation” across multiple industries. The objective is not simply to introduce new technologies but to improve productivity throughout the broader economy by integrating advanced digital capabilities into industrial production.
Economists note, however, that substantial implementation work remains ahead. Takeuchi said the blueprint contains the necessary policy direction to pursue its growth objectives, but many operational details still need to be developed. The government expects private companies to match public investment if overall capital expenditure targets are to be achieved, while technological advances, particularly through AI, will need to generate significant productivity improvements.
Under the government’s projections, total factor productivity, which measures the additional output generated through more efficient use of labour and capital, would need to more than double during the 2036-2040 period compared with the average recorded between 2021 and 2025. That projection reflects the government’s expectation that public investment can stimulate a broader increase in private-sector productivity rather than functioning solely as a programme of increased state spending.
Takuya Hoshino, economist at Daiichi Life Research Institute, said sustained one per cent economic growth would also require structural reforms alongside investment. Measures to improve labour market liquidity, he noted, would be needed to address supply constraints that continue to affect Japan’s economy, indicating that investment alone may not be sufficient to meet the government’s long-term objectives.
The blueprint also introduces a significant shift in the way Japan approaches fiscal management. For decades, policymakers have placed considerable importance on achieving a primary budget balance, measuring whether government revenues can cover spending excluding interest payments. Under the new framework, greater emphasis will instead be placed on ensuring that the country’s debt-to-GDP ratio declines steadily over time. This approach allows the government greater flexibility to accept temporary deterioration in the primary balance where it considers such spending necessary to support long-term growth.
To support that strategy, the government plans to establish a separate investment framework for what it describes as a “strong and prosperous Japan”. Distinct from the regular annual budget, the mechanism will finance multi-year projects forming part of the broader growth strategy. The framework will not impose a ceiling on investment spending, with financing provided through temporary government bonds that are expected to be repaid through dedicated future funding sources.
Financial markets have responded cautiously to these changes. Long-term Japanese government bond yields rose sharply after a draft version of the blueprint was released at the end of June, although yields later eased following other developments, including comments by Finance Minister Satsuki Katayama encouraging the country’s pension fund to increase investment in Japanese financial assets.
The earlier draft also attracted attention because it referred to the Bank of Japan being expected to coordinate closely with the government on monetary policy, leading some investors to interpret the language as signalling pressure on the central bank to moderate future interest rate increases. The final version of the blueprint removed those concerns by stating that decisions on monetary policy would remain the responsibility of the Bank of Japan.
Even so, questions remain over the broader fiscal implications of the government’s strategy. Takeuchi said shifting the focus from the primary balance to the debt-to-GDP ratio could increase the risk of weaker fiscal discipline. Hoshino described the emphasis on debt relative to economic output as a reasonable approach because it better reflects the impact of higher interest payments as borrowing costs rise. At the same time, he noted that future fiscal plans will depend heavily on economic growth forecasts that may prove optimistic, while the government has yet to disclose the overall scale of bond issuance or the timetable for repaying debt linked to its proposed “strong and prosperous Japan” investment framework.
As Japan embarks on one of its most ambitious long-term economic strategies in recent years, the government’s ability to convert large-scale public investment into sustained productivity growth, stronger private-sector participation and durable economic expansion will remain central to the implementation of the blueprint approved by Prime Minister Sanae Takaichi’s cabinet, according to details reported by Nikkei Asia.
