Japan's chemical industry reshuffling accelerates in an AI-driven market
Morgan Stanley believes Japan's chemical industry is shifting from basic chemicals toward high-value-added functional materials. Petrochemical valuations are low and restructuring momentum is strengthening; electronic chemicals are supported by AI and a recovery in mature semiconductors; and fine chemicals are benefiting from improving aerospace and carbon fiber demand.
- The industry view on petrochemical majors is “Attractive.” Demand and ethylene operating rates remain weak, but prices and spreads may be nearing a bottom, while capacity reductions in Japan and South Korea and China's anti-involution policies are improving industry sentiment.
- Recommended stocks include Zeon (4205), Sumitomo Chemical (4005), Toray (3402), Asahi Kasei (3407), and Shin-Etsu Chemical (4063).
- The industry view on electronic chemicals is “In-Line.” AI semiconductor expansion and a gradual recovery in mature semiconductors are jointly supporting demand, while 300mm silicon wafers are on a recovery trend.
- The industry view on fine chemicals is “In-Line.” Full recovery in aerospace applications is driving a significant improvement in carbon fiber composite revenue, with Toray identified as the top pick.
Report interpretation
Overview
This report is Morgan Stanley's investor presentation on Japan's chemical industry, covering three major segments: petrochemical majors, electronic chemicals, and fine chemicals. Its core view is that Japan's chemical industry is undergoing industrial restructuring and business portfolio transformation; basic chemicals are pressured by China's supply expansion and weak domestic demand, but signs of a bottom are increasing; electronic chemicals are supported by AI semiconductor expansion and recovering mature semiconductor demand; and carbon fiber materials in fine chemicals are driven by the recovery of aerospace applications and tightening medium-term supply and demand.
Core views
The report's most positive segment is petrochemical majors, where it believes valuation indicators remain low, share prices are generally undervalued, and restructuring momentum in Japan's petrochemical industry is strengthening. The outlook for electronic chemicals remains one of steady growth, but with greater emphasis on stock selection, favoring Zeon and Shin-Etsu Chemical. Fine chemicals are rated neutral overall, but Toray is the top pick due to its leading carbon fiber business share and advantages in textiles and functional chemicals.
Analysis framework
The report combines analysis of industry supply and demand, prices and spreads, capacity utilization, market capitalization performance, global peer valuations, business portfolio transformation, and company earnings forecasts. The petrochemical section focuses on ethylene supply and demand, reductions in naphtha crackers, Asian petrochemical spreads, and restructuring of Japanese olefin complexes; the electronic chemicals section focuses on AI semiconductors, mature semiconductors, 300mm silicon wafer inventories and shipments; and the fine chemicals section focuses on aerospace composites, carbon fiber supply and demand, Boeing deliveries, and general industrial application demand.
Methodology notes
The position of the petrochemical cycle is assessed through ethylene operating rates, Asian petrochemical prices and spreads, domestic demand, and export trends.
The report believes petrochemical demand and ethylene operating rates remain weak, but global ethylene operating rates have risen moderately after bottoming in 2023, while Asian petrochemical prices and spreads appear close to a bottom.
Japanese chemical companies are compared with global peers using P/E, P/CF, EV/EBITDA, P/B, dividend yields, and market capitalization performance.
The report notes that investment indicators in the petrochemical segment remain low and stocks appear broadly undervalued, while recommended stocks are selected based on differences between target prices and current share prices.
Companies are assessed on whether they are shifting from basic chemicals vulnerable to cyclical fluctuations toward functional chemicals with higher margins and stronger resilience across cycles.
The report believes Japan's chemical industry is reshaping its business structure, with restructuring, capacity optimization, and growth investment serving as important drivers of future earnings improvement.

Impact & implications
For investors, the implication is that opportunities in Japan's chemical industry no longer come solely from a cyclical rebound, but increasingly from industrial restructuring, capacity optimization, and exposure to high-value-added materials. The petrochemical segment may offer valuation recovery and restructuring catalysts; electronic chemicals provide exposure to AI and semiconductor recovery; and carbon fiber in fine chemicals provides exposure to recovery in aerospace and industrial applications.
Risks
- Petrochemical demand and ethylene capacity utilization remain weak, and prices and spreads may lack sustained recovery momentum.
- China's ethylene production has increased substantially since 2020 and may continue to pressure Asian petrochemical supply and demand.
- If restructuring in Japan's petrochemical industry proceeds more slowly than expected, valuation recovery may be delayed.
- Silicon wafer customer inventories remain high in electronic chemicals, and the recovery trend for 300mm silicon wafers may be uneven.
- If U.S. PVC prices and housing starts fall short of expectations, the recovery in Shin-Etsu Chemical-related earnings may be affected.
- If aerospace composite and carbon fiber demand recovers less than expected, Toray's upside thesis may be impaired.
- Morgan Stanley discloses business relationships with some covered companies, and investors should consider potential conflicts of interest.
What to watch
- Whether Asian petrochemical prices and spreads continue to confirm a bottom.
- The actual progress of Japanese olefin complex and ethylene facility integration, particularly optimization plans related to Chiba Ichihara, Chiba Keiyo, and western Japan.
- Whether China's anti-involution policies and reductions in South Korean naphtha crackers materially improve regional supply and demand.
- Changes in 300mm silicon wafer shipments, capacity, and months of inventory.
- The transmission of AI semiconductor and mature semiconductor demand recovery to electronic chemicals orders.
- U.S. domestic and export PVC prices, North American PVC spreads, U.S. housing starts, and 30-year mortgage rates.
- Boeing deliveries, aerospace composite demand, carbon fiber inventories, and operating rates.
- Whether Mitsubishi Chemical Group can deploy approximately ¥510 billion in proceeds from the sale of its pharmaceutical subsidiary into growth investments and create new growth drivers.
