Business Details

The company manufactures and sells original pharmaceuticals, generic pharmaceuticals, medical devices, and in vitro diagnostic products, centered on the ophthalmology field. It promotes appropriate use and provides safety information to medical institutions and wholesalers through MRs. In FY2026 (ending March 2026), the company has expanded its contribution to medical practice through the resumption of supply of Macuaid for Intraocular Injection, the launch of the new generic drug Epinastine Hydrochloride LX Ophthalmic Solution 0.1%, the transfer of manufacturing and marketing rights for an ophthalmic surgical adjuvant, and the launch of the AcrivaTrinova Pro multifocal intraocular lens and its toric model.

Recent Overview

Revenue increased 37.1% due to the resumption of Macuaid supply and new product launches, while the loss also narrowed significantly

Revenue in the Pharmaceuticals Business for FY2026 (ending March 2026) was ¥4,762 million (up 37.1% year on year). The resumption of supply of Macuaid for Intraocular Injection in April 2025 was the largest contributing factor to the increase. The new launch of Epinastine Hydrochloride LX Ophthalmic Solution 0.1%, the transfer of manufacturing and marketing rights for an ophthalmic surgical adjuvant, and the launch of the AcrivaTrinova Pro multifocal intraocular lens and its toric model also contributed. On the other hand, sales of products such as Dicloud Ophthalmic Solution declined due to the impact of the selection-based treatment system for long-listed products implemented in October 2024. The segment loss was −¥674 million, narrowing from −¥1,086 million in the prior period. Major sales destinations were Mediceo Corporation (¥1,241 million) and Suzuken Co., Ltd. (¥1,081 million).

Key Products

product
Macuaid for Intraocular Injection

A flagship original product whose past supply suspension significantly impacted business results. Supply resumed from April 2025, with the company promoting early delivery both domestically and overseas (including for the Global Business). The impact of drug price revisions, including the repayment associated with the new drug creation premium, is expected to affect revenue from FY2027 (ending March 2027) onward.

product
Epinastine Hydrochloride LX Ophthalmic Solution 0.1%

A generic drug newly launched in FY2026 (ending March 2026). It expands the lineup in addition to the existing Epinastine Hydrochloride Ophthalmic Solution, contributing to sales growth in the generic drug business.

product
Carteolol Hydrochloride LA Ophthalmic Solution / Tafluprost Ophthalmic Solution / Epinastine Hydrochloride Ophthalmic Solution

A group of generic drugs capturing substitute demand from long-listed products. Continued sales growth was achieved in FY2026 (ending March 2026) as well, offsetting revenue declines caused by the selection-based treatment system impact on long-listed products such as Dicloud Ophthalmic Solution.

product
Sodium Hyaluronate Ophthalmic Viscoelastic Agent

An ophthalmic surgical adjuvant for which manufacturing and marketing rights were transferred in FY2026 (ending March 2026). The company has explicitly identified it as a factor for sales increase in FY2027 (ending March 2027), contributing to the expansion of the Pharmaceuticals Business lineup.

product
AcrivaTrinova Pro (Multifocal Intraocular Lens)

AcrivaTrinova Pro was launched in June 2025, and the toric model, AcrivaTrinova Pro Toric, was launched in January 2026. This marked entry into the intraocular lens market as a new development within the medical device business. Increased selling expenses associated with the launch have pressured short-term profitability.

product
Sub-Tenon Injection Needle

Launched in April 2025 as a medical device used in ophthalmic surgery and procedures. Part of a full-lineup strategy in ophthalmology combining pharmaceuticals and medical devices.

product
In Vitro Diagnostic Products (Capilia Adeno Eye Neo, etc.)

In vitro diagnostic products whose sales are affected by the prevalence of infectious diseases. They form part of the lineup covering diagnosis through treatment in the ophthalmology field.

Growth Drivers

  • Full-scale recovery of original product sales (domestic and overseas) driven by the resumption of Macuaid for Intraocular Injection supply
  • Expansion of the medical device business through the AcrivaTrinova Pro multifocal intraocular lens and its toric model, AcrivaTrinova Pro Toric
  • Continued sales growth of generic drugs (Carteolol Hydrochloride LA Ophthalmic Solution, Epinastine Hydrochloride Ophthalmic Solution, Tafluprost Ophthalmic Solution)
  • Lineup expansion through the launch of the new generic drug Epinastine Hydrochloride LX Ophthalmic Solution 0.1% and the transfer of manufacturing and marketing rights for an ophthalmic surgical adjuvant (Sodium Hyaluronate Ophthalmic Viscoelastic Agent)
  • Strengthening MR activity levels and deepening cooperation with wholesalers (Mediceo Corporation, Suzuken Co., Ltd.)
  • Expansion of business opportunities through a full-lineup strategy in ophthalmology (original pharmaceuticals, generic pharmaceuticals, medical devices, in vitro diagnostic products)

Risks

  • Continued downward pressure on revenue from annual drug price revisions (the company has explicitly identified the impact of the new drug creation premium repayment for Macuaid for Intraocular Injection in FY2027, ending March 2027)
  • Continued decline in sales of products such as Dicloud Ophthalmic Solution due to the implementation of the selection-based treatment system for long-listed products (October 2024)
  • Risk of product supply suspension (the past supply suspension of Macuaid for Intraocular Injection had a significant impact on business results)
  • Fluctuations in sales of in vitro diagnostic products depending on the prevalence of infectious diseases such as epidemic keratoconjunctivitis
  • Short-term profit pressure from increased selling, general and administrative expenses associated with the launch of medical devices (such as intraocular lenses)
  • Uncertainty regarding market penetration of new products (such as intraocular lenses), including market share, selling prices, and competitive dynamics
  • Risk of supply suspension in the event of a disaster or accident, as the company has only one production site, the Sagamioi Plant
