China's Prolonged Domestic Demand Slump — The Pressure on Japanese Manufacturers to Restructure Their Export Destinations

Lead

China's real GDP growth rate slowed to 4.2% year-on-year in the April–June quarter of 2026, falling short of the government's target of "around 5%." According to preliminary trade data from Japan's Ministry of Finance, Japanese exports to China posted year-on-year declines for four consecutive months from April through July. What matters here is not the cyclical peaks and troughs, but the fact that China's consumption structure itself is undergoing a fundamental shift.

What Is Happening

According to the August preliminary trade data released by the Ministry of Finance on September 8, exports to China fell 8.3% year-on-year. Automotive parts dropped 14.2% year-on-year, while semiconductor and other electronic components fell 9.7%, with the core categories of Japan's manufacturing sector declining across the board.

Looking at data from the Chinese side, retail sales in August as reported by the National Bureau of Statistics rose only 2.1% year-on-year — far below the average of 4–5% recorded since 2024. Continued declines in real estate prices are compressing household balance sheets, which in turn is suppressing consumption.

Voices on X have raised concerns as well:

"Many companies' IR communications are brushing off the decline in exports to China as 'inventory adjustment,' but one look at local consumer confidence indices makes it clear that a prolonged slump is unavoidable."

Background

China's domestic demand slump originates in the adjustment of the real estate sector. Since 2021, liquidity crises among major property developers have cascaded, and the floor area of new housing starts contracted by roughly another 30% compared to 2023 levels in the first half of 2026 (National Bureau of Statistics). In China, where real estate assets account for 60–70% of household wealth, falling prices deal a direct blow to consumer sentiment.

The IMF's July revised World Economic Outlook lowered China's 2026 growth forecast to 4.3%, down 0.4 percentage points from its April projection. Household savings rates have resumed an upward trend entering 2026, and the scenario of domestic demand-led growth is receding.

In the short term, fiscal spending from autumn onward — centered on infrastructure stimulus — may provide some support. However, historical analogies suggest that repairing real estate balance sheets takes anywhere from five to ten years — just as it did in Japan during the 1990s.

Key Points to Watch

Industrial Sectors with High Dependence on China

China's share of Japan's total exports stands at approximately 19% (2025 Ministry of Finance finalized figures). Machine tools have a China-bound ratio exceeding 35%, leaving them directly exposed to any contraction in capital expenditure by Chinese manufacturers. Automobiles and chemicals also carry high ratios, making this a cross-sectoral risk.

Southeast Asia and India as Alternative Markets

A shift toward ASEAN and India has attracted attention, but at present neither market offers a large enough base or sufficient infrastructure to substitute for China. Japan's export share to India stands at only around 3.2% as of 2026 (Ministry of Finance). A structural transition will require a considerable amount of time.

Local Procurement Shift by Japan-Affiliated Companies in China

As Japan-affiliated companies operating in China increase local procurement, the volume of exports from Japan itself also declines. This channel is altering the structure of business with China in ways that are difficult to detect in export statistics, and warrants close attention.

Editorial Perspective

Having spent five years covering the Bank of Japan's Monetary Policy Meetings, I can say with confidence that disruptions in external demand always feed back into domestic monetary policy. When exports are dragged down, corporate earnings are squeezed and the financial capacity for wage increases shrinks. If the pace of recovery in real wages slows, the BOJ's scenario of "sustainable price stability" may itself require revision.

What I am watching closely is how Japanese companies will behave in terms of investment if the slump becomes prolonged. Whether they direct capital expenditure toward domestic operations or disperse it across third countries will dramatically reshape the employment and wage landscape several years from now. As I organized in a paper cited in an IMF report during my think tank days, the chain linking interest rates, growth, and investment cannot be understood in its essence unless viewed across a 30-year horizon.

Framing this by time horizon: in the short term, we are in a phase of "searching for a bottom through inventory adjustment and stimulus"; in the medium term, "the prolonged repair of the real estate sector and a structural contraction of exports to China"; and in the long term, "the entrenchment of export diversification toward Southeast Asia and India." Layering these three levels changes how one reads today's trade statistics.

I want to make judgments by lining up primary sources. Cross-referencing three sources — the Ministry of Finance's trade statistics, the National Bureau of Statistics' monthly indicators, and the IMF's World Economic Outlook — reveals just how hollow the word "temporary" really is.

Summary

China's domestic demand slump is not a simple recession but a compound problem in which consumption structure and real estate balance sheets are deeply intertwined. Japanese manufacturers have entered a phase in which they must engage in earnest discussion about diversifying their export destinations.
