Notice of participation in 'JECA FAIR 2026 - The 74th Electrical Installation Industry Exhibition' from May 27 (Wednesday) to May 29 (Friday), 2026.

[Official Release] Waterproof Sleeve for Underground Walls "Pipe-in-Sleeve" (Abbreviated as PIS) Reducing Labor at Construction Sites! Enhancing Waterproof Performance of Buildings!

■Recently, our "Pipe-in-Sleeve," showcased at the JECA Fair 2025, is officially launched with great anticipation.■ In the underground wall section (underground beam sleeve), we have pre-treated the PVC sleeve and the outer space (gap) of the FEP with "waterproof treatment" at the factory, making it prefabricated for the site. No cumbersome work is required on-site; after the PIS installation, only joint connections are basically needed. Ensuring stable waterproofing! Achieving work efficiency and promoting flood prevention and water resistance. This is an innovative and advanced product for underground beam sleeve construction. <Features> ■ Excellent waterproof performance [Flood prevention and water resistance promotion] ■ Proposal for labor-saving at construction sites ■ Adaptable to individual design specifications of construction projects ■ Improved work efficiency, standardized quality, and enhanced maintenance [To designers and contractors] FEP pipe routing, bell mouth terminal installation, connection of different types of pipes (AQ type), and various connection parts of FEP can be arranged to fit the specifications of individual construction sites! Furthermore, it can also respond to unexpected leaks! It combines maintenance and serviceability, making it a versatile and highly adaptable product.

Reduction of work on the outer wall of the underground beam (underground beam sleeve) and enhancement of waterproofing performance.

With the increase in building height and seismic resistance improvements, the width of beams has been increasing. - Increased amount of rebar (main bars and stirrups) in beams - Spread of high-strength concrete - Long-period and wind sway countermeasures - Increased load on beams due to the slimming of columns (design requirements) - Improved workability (especially with high-strength concrete) As a result of these factors, recent high-rise buildings show an increase in "beam width," particularly for underground beams, which tend to be significantly thicker, with widths exceeding 1,000 mm not being uncommon. Therefore, waterproofing work for the outer circumference of cable conduits penetrating through sleeves in underground exterior wall sections (underground beams) is extremely challenging. Due to the current shortage of construction workers and skilled labor, the waterproof performance of buildings is becoming increasingly unstable. Thus, we propose the following: **Application Scenarios** - Piping work for underground beams - Sleeve penetration work for exterior walls - Pulling through FEP pipes **Benefits of Implementation** - Significant reduction in construction time - Reduced burden on workers - Stabilization of quality - Decreased risk of water leakage

We are pleased to announce that Gywood has been recommended as a featured building material in the special project "Recommended Building Materials" at the Housing Business Fair within the comprehensive exhibition for housing, architecture, and real estate [BREX Kansai]. We will be exhibiting in the "Recommended Building Materials and Equipment" zone, where professionals from the field gather to showcase their recommended materials. We invite everyone to stop by and visit us.

Seminar Overview As the labor shortage in manufacturing sites becomes more severe, the labor costs and time losses associated with the "transportation" of products and components, as well as "cleaning" within factories, have become critical management issues that cannot be overlooked. In this webinar, we will introduce the latest use cases of "Autonomous Mobile Robots (AMR)" and "Commercial Cleaning Robots" that achieve productivity improvements in manufacturing environments. We will specifically address questions such as "How are other companies operating these technologies?" and "What kind of cost reduction effects can be expected after implementation?" by providing concrete explanations of actual before-and-after scenarios and operational flows. Factory managers and members of production technology and DX promotion departments who want to advance automation and efficiency on-site are encouraged to participate! Recommended for: - Those who are unsure about where to start with automation, labor reduction, and DX in their factories. - Those who want to alleviate labor shortages on-site and focus resources on core operations to improve productivity. - Those who want to stay updated on the latest trends in the use of transportation robots (AMR) and cleaning robots.

Our representative, Koichi Yokoyama, will be speaking at an online seminar scheduled for November 27 (Friday). Participation is possible from anywhere in the country. We hope you will join us! 【Event Overview】 Date: November 27, 2026 (Friday) 13:00 - 15:05 (Deadline: November 25, 17:00) Venue: Online (Zoom) / Participation Fee: Free (Pre-registration required, lottery system) Organizer: Otsuka Shokai Co., Ltd. 【Session Details (14:05 - 14:35)】 "What Does Reliable Data Creation Mean? - Insights from Certified Public Accountants and Tax Accountants on Creating Trustworthy Data Before Relying on AI" We will discuss the quality and reliability of data that influences AI outcomes, covering points such as "Considerations for Practicing DX" and "Data Integrity and Authenticity" from the perspectives of certified public accountants and tax accountants, to lay the groundwork for safely utilizing AI. *Applications from competitors or similar industries may be declined. *Inquiries: Otsuka Shokai Co., Ltd.
