Japan's GDP growth could drop to near-zero by 2040 unless AI and reforms prevent economic stagnation.
The episode begins with host Machida Tetsu introducing the Japan Center for Economic Research's 15-year economic forecast. The standard scenario predicts Japan's real GDP growth gradually declining to the low 0% range by 2040, with primary balance remaining negative and government debt-to-GDP ratio rising again after temporary decline. The reform scenario maintains growth around 1% through AI adoption, regulatory reforms, and industrial transformation. The host expresses relief that even the standard scenario avoids negative growth despite Trump's tariff policies, then questions how damaging those policies actually were. The guest explains that tariff impacts were masked by global AI demand expansion and yen depreciation boosting inbound tourism. The conversation shifts to oil price shocks from US-Israel actions against Iran, with simulations showing a 50% oil price increase would reduce Japan's GDP growth by 0.3 percentage points in the first year. The second half focuses on the reform scenario, emphasizing AI's role in productivity growth. The guest details Japan's significant lag in AI adoption: only 50% of companies use generative AI compared to over 90% in the US, China, and Germany, with personal usage at just 20% versus China's 80%. Even in robotics, once a Japanese strength, 90% of humanoid robot shipments in 2025 were Chinese-made. The reform scenario assumes Japan's AI adoption will lag the US by 3-6 years, potentially widening competitiveness gaps. Fiscal aspects include taxing annual incomes over 15 million yen instead of consumption tax cuts, with defense spending rising to 3.5% of GDP by 2035, funded by corporate taxes. The episode concludes with labor market reforms needed alongside AI adoption, addressing non-regular employment growth under Abenomics and the need for wage increases to maintain social stability as AI potentially reduces labor's share of value.
