We will exhibit Oji's cellulose nanofiber at the "2024 NAGOYA Automotive Technology Exhibition."

It is a natural-derived high-performance additive that has functions such as high viscosity and high transparency, which are superior to conventional additives.

"AUROVISCO" is a water dispersion of ultra-fine wood fiber cellulose nanofiber (CNF) with a fiber width of 3nm. By adding just a small amount to water-based liquid agents, the following outstanding functions are expected to be imparted. <Functions> - High transparency - High viscosity - dispersion stability - Water retention - Coating stability function - Thixotropic <Applications> - Thickening and dispersing agents for paints and inks: dispersion stability of pigments and additives / coating film stability - Cleaning and disinfectant solutions: dispersion of abrasives, etc., and coating film stability after application of liquid agents - Ceramic products such as concrete: reinforcement effect for ceramic products *The Oji Group has adopted the "phosphate esterification method" as an effective technique to reduce the energy used for fine processing during manufacturing. This method enables the production of high-quality (high transparency, high viscosity, thixotropic) cellulose nanofibers with higher production efficiency compared to conventional methods. In 2017, the cellulose nanofiber production facility began operation at the Oji Paper Tomioka Plant.

• Concrete admixture

Biomass content over 80% - Transparent, high-strength sheets made primarily of cellulose nanofibers / Further enhancement of functionality through composite with other materials!

The cellulose nanofiber transparent sheet "AUROVEIL" boasts glass-like transparency and dimensional stability while being made from wood-based materials. Additionally, it features high strength, high elasticity, and good flexibility. ■ Features of "AUROVEIL" - High transparency / High strength / High elasticity / Flexibility / High dimensional stability - Biomass content: Approximately 80% (depending on required functions and specifications, please contact us for details) ■ Composite Cellulose Nanofiber Sheet We have established a technology to combine cellulose nanofiber sheets (AUROVEIL) with resins such as "polycarbonate" and "acrylic." This environmentally friendly composite material reduces the use of fossil-based and plastic materials while leveraging the characteristics of each material. * "Cellulose nanofiber" refers to fibers that have been finely disassembled to the nano level (one millionth of a millimeter) from cellulose, the main component of wood. It is said to be a "dream new material" that is one-fifth the weight of steel yet possesses more than five times its strength. Being plant-based, it is also attracting attention as a sustainable resource.

New rubber products for the carbon-neutral era. Natural rubber × natural materials: cellulose nanofiber rubber composite CNF masterbatch.

This is a rubber composite masterbatch that combines unique phosphoric acid esterified CNF and natural rubber. Even with a small amount of addition, it improves elasticity and provides excellent strength and elongation, making it an environmentally friendly material that is expected to reduce the amount of carbon black derived from petroleum. <Features> Biomass Material... By replacing carbon black, the ratio of natural materials increases. Enhanced Functionality... Hardness and elongation comparable to or exceeding that of carbon black. Energy Saving & Durability... Increased durability is expected due to effects such as improved strength. Design Flexibility... The milky white masterbatch allows for consideration of colorful variations. Customization... We also accept requests for compatibility with synthetic rubbers such as NBR and HNBR, as well as optimization of fiber shapes. * "Cellulose Nanofiber" refers to fibers that have been finely disassembled to the nano level (one millionth of a millimeter) from cellulose, the main component of wood.

The "Wallet Key," which brings a major innovation to the hotel key situation that has undergone several generations of changes, including cylinder locks, magnetic locks, contactless card locks, and mobile keys, has finally been born. Full-scale implementation will begin within the year at domestic accommodations. This service directly delivers the Wallet Key to the wallet apps pre-installed on guests' smartphones. We will provide an overview and the latest information on hotel keys from the perspectives of business efficiency, energy conservation, and hotel digital transformation (DX).

The Aica Modern Architecture Seminar Executive Committee will invite architect Junya Ishigami as a lecturer and hold the "67th Aica Modern Architecture Seminar." The "Aica Modern Architecture Seminar" is a cultural activity aimed at enhancing and developing architectural culture, welcoming renowned architects from both Japan and abroad to give lectures across a wide range of fields, including housing, environment, and urban space. This seminar, which began in 1983, will mark its 67th session, and the details of the event are as follows. We sincerely look forward to your attendance. Organizer and others: ■ Organizer: Aica Modern Architecture Seminar Executive Committee ■ Sponsor: Aica Kogyo Co., Ltd. ■ Operational Support: Kenpo Co., Ltd. ■ Inquiries: Aica Modern Architecture Seminar Executive Committee Office (within Kenpo Co., Ltd.) aicaseminar@kenchiku.co.jp

NR-Power Lab Co., Ltd. will exhibit at CEATEC 2025, which will be held at Makuhari Messe from Tuesday, October 14, 2025, to Friday, October 17, 2025. We will be jointly exhibiting with our investors, NGK Insulators and Ricoh. Our company is contributing to the market expansion of the Energy Resource Aggregation Business (ERAB) through the development of energy resource IoT systems, while also working on the development of diverse service businesses. The services we are currently developing are mainly two: the "GX Data Utilization Service," which creates environmental value, and the "Virtual Power Plant Service (VPP)," which generates power "adjustment capability" by automatically controlling batteries and other devices using AI. At our booth, we will introduce specific demonstration cases of these services. We look forward to your visit.
