Nihon Yamamura Glass Co., Ltd. 5210

Business

Nihon Yamamura Glass Co., Ltd. was founded in 1914, and the current corporate structure was established in 1998 through the merger of Yamamura Glass and Nippon Glass. The group, comprising the company along with 14 subsidiaries and 2 affiliated companies, operates in four segments: manufacture and sale of glass bottles (its core business), plastic containers such as beverage caps, logistics including transportation, storage and on-site operations, and New Glass Business for electronics and semiconductors. Its main customers are beverage, food, and pharmaceutical manufacturers, among others. In addition to three domestic plants (Tokyo, Harima, and Saitama), the company has production and sales bases across Asia, including China, Thailand, and the Philippines. Consolidated net sales for FY2026 (ending March 2026) were ¥72,190 million.

Business Model

A vertically integrated model in which the company manufactures glass bottles, plastic containers, and New Glass in-house and supplies them to customers through group logistics subsidiaries. Sales of equipment such as bottle-making machines and conveyance devices, as well as technical assistance, are also revenue sources. In phases of declining demand, the company raises unit prices through price revisions and a shift toward high-value-added products, while maintaining profit margins through fixed-cost control such as reductions in depreciation expenses. Equity-method investment gains from overseas affiliates also contribute to ordinary income.

Company Strengths

The company maintains a self-contained group structure spanning manufacturing (glass bottles, plastic containers, New Glass) through to logistics (Yamamura Logistics, Nakayama Unso). In FY2026 (ending March 2026), the Logistics segment achieved sales of ¥14,785 million, with new outsourced operations secured through intra-group synergies. The integrated operation of manufacturing and logistics underpins stable supply capability for customers.

The company possesses the technical capability to design and manufacture equipment such as bottle-making machines and conveyance systems in-house, and sell them both domestically and overseas. In FY2026 (ending March 2026), increased sales of bottle-making related equipment in the Glass Bottles Business contributed to higher profit, with segment profit reaching ¥2,883 million (up 28.2% year on year). The company is also advancing joint research with overseas glass bottle manufacturers through its participation in IPGR.

The company established the New Glass Research Institute in 1987 and has continued developing products such as Glass for Electronic Components, Glass Ceramics Products, and Cap Components for Optical Communications. In FY2026 (ending March 2026), sales in the New Glass Business reached ¥3,522 million (up 13.3% year on year), with segment profit growing sharply to ¥434 million (up 79.2% year on year). Development of large-area glass ceramic substrates for semiconductor applications is also underway through technical collaboration with a Taiwanese partner.

ENVALITH's Perspective

In FY2026 (ending March 2026), operating profit reached ¥3,772 million (up 21.4% year on year) and ordinary profit reached ¥4,388 million (up 36.5% year on year), marking a recovery. However, the company's forecast for FY2027 (ending March 2027) calls for a substantial profit decline, with operating profit of ¥1,800 million (down 52.3% year on year) and ordinary profit of ¥2,200 million (down 49.9% year on year). Whether the strong performance seen in FY2026 (ending March 2026) is sustainable is the focal point. The disappearance of equity-method investment gains and trends in raw material and fuel costs are recognized as downside risks.

Domestic demand for glass bottles continues on a gradual decline due to a shift toward containers made of other materials and the declining birthrate and aging population. In FY2026 (ending March 2026), sales of the Glass Bottles Business also declined to ¥45,189 million (down 4.4% year on year). Segment profit increased to ¥2,883 million (up 28.2% year on year) thanks to price revisions and improvements in product mix, but the structural issue of declining shipment volumes has not been resolved. The ability to maintain profitability once the effects of price revisions run their course will be a key point for medium- to long-term evaluation.

The equity ratio stood at 58.2% (versus 57.8% in the previous fiscal year), and the market-value-based equity ratio improved to 29.4% (versus 23.2% in the previous fiscal year), showing improving trends in both financial soundness and equity value. The annual dividend for FY2026 (ending March 2026) was increased to ¥150 (from ¥135 in the previous fiscal year), bringing the payout ratio to 46.9%, closer to the company's target guideline of around 50%. A dividend of ¥150 is also planned for FY2027 (ending March 2027), but against the forecasted net profit of ¥2,300 million, the payout ratio is expected to significantly exceed the guideline at 66.7%, raising questions about the company's ability to maintain dividends in the event of deteriorating performance.

Growth Strategy

Under the new medium-term management plan "Leap Forward for Sustainable Growth," the company is advancing the strengthening of existing businesses and the development of new businesses.

The structural decline in shipment volume is being offset through price revisions and optimization of the product mix. In FY2026 (ending March 2026), segment profit reached ¥2,883 million (up 28.2% year on year). Expanded external sales of Bottle-Making Equipment & Machinery also contributed to revenue diversification. The company plans to continue investing in labor-saving and production efficiency improvements.

The company is promoting expanded shipments and price revisions for Glass for Electronic Components and Glass Ceramics Products for semiconductors. In FY2026 (ending March 2026), segment revenue increased 13.3% and segment profit increased 79.2%. Capital expenditure of ¥100 million was made to continue enhancing production capacity.

The company is expanding production scale through the relocation of its Chinese subsidiary's factory. Capital expenditure in FY2026 (ending March 2026) reached ¥1,014 million, implemented to enhance production capacity. Increased manufacturing fixed costs, such as land lease fees, are temporarily weighing on profit, but cost improvement effects are expected once production scale expansion is complete.

Under the "Strengthening the Financial Base" policy of the previous medium-term management plan (FY2023 to FY2026, ending March 2026), the equity ratio improved significantly from 41.0% (FY2022, ending March 2022) to 58.2% (FY2026, ending March 2026). Interest-bearing debt was also reduced by ¥2,267 million. The annual dividend was increased from ¥135 to ¥150, achieving a dividend payout ratio of 46.9%.

A new three-year medium-term management plan will start in April 2026. The company is promoting the strengthening of existing businesses and the development of new businesses to realize the group's management vision of being "a company needed even 100 years from now." With a goal of achieving ROE in excess of the cost of shareholders' equity, the company has also refined its segment management (reclassifying part of the Logistics Business into the Glass Bottles Business).
