These Japanese AI winners don't make chips. They make toilets, glass fiber and seasoning

• Toto's advanced ceramics business (which makes electrostatic chucks for semiconductor equipment) saw 34% revenue increase and 42% jump in operating profit, offsetting declines in its core housing equipment unit.
• Nittobo's electronic materials segment contributed 91% of the company's total net sales increase, with operating profit jumping 39.7% year-over-year driven by demand for its T-glass product used in AI servers and semiconductor substrates.
• Ajinomoto's 'Healthcare and Others' segment, which includes ABF insulating film for high-performance chips, saw business profit surge 45.1% and now surpasses the company's frozen food segment in both revenue and profit.

Summary: Japanese AI Beneficiaries Beyond Semiconductors

Key Companies and Products

Three Japanese companies are capitalizing on the AI boom through unexpected semiconductor-related businesses: Toto (toilets), Nittobo (textiles/glass fiber), and Ajinomoto (MSG seasoning). Their connections to chips lie in specialized materials:

• Toto: Manufactures ceramic electrostatic chucks for semiconductor equipment
• Nittobo: Supplies advanced glass fiber for semiconductor package substrates (T-glass product)
• Ajinomoto: Produces ABF (build-up film) insulating material for high-performance chips and data center servers

Financial Performance (FY ending March 31, 2025)

Toto's Advanced Ceramics segment saw revenue jump 34% and operating profit surge 42%, offsetting declines in its core housing equipment business. The company has manufactured electronic chucks since 1988 but maintains "no plans" to pivot from its traditional toilet business.

Nittobo's Electronic Materials division drove 91% of the company's net sales increase, with revenue climbing 20.4% and operating profit surging 39.7% (+5.5 billion yen or ~$34 million). The company is "proactively strengthening efforts to expand production capacity" for data center and AI server applications.

Ajinomoto's Healthcare and Others segment—which includes ABF—saw revenue rise 4% and business profit jump 45.1%, now exceeding its frozen food segment. ABF, commercialized in 1999, derived from MSG manufacturing byproducts.

Market Implications

These companies demonstrate how diversified manufacturers are capturing AI infrastructure demand beyond traditional chipmakers. All three plan balanced growth strategies while scaling semiconductor-related capacity to meet surging data center and AI server requirements. The semiconductor components provide higher margins but remain volatile compared to traditional business lines.
