"Advanced Construction, Disaster Prevention, and Mitigation Technology Fair in Kumamoto Contributing to Creative Reconstruction" It has been two years since the Kumamoto earthquake occurred in April 2016. We would like to express our heartfelt gratitude for the warm support and condolences we have received from everyone. Nearly 40,000 people are still living in temporary housing, and while the reconstruction is still ongoing, we will continue to make steady progress with the support of all parties involved. This time, aiming for the recovery and reconstruction from the Kumamoto earthquake and the establishment of a rich, safe, and secure social infrastructure, we will hold the "Advanced Construction, Disaster Prevention, and Mitigation Technology Fair in Kumamoto" to promote the establishment of disaster prevention, mitigation, and business continuity plans (BCP) across various industrial sectors and to encourage wide-area cooperation during disasters. We hope that many of you will participate and that this fair will contribute to the improvement of construction technology and further promotion of disaster prevention measures. Chairman of the Organizing Committee for the Advanced Construction, Disaster Prevention, and Mitigation Technology Fair in Kumamoto (Governor of Kumamoto Prefecture) Ikki Kamishima

The large-scale business exhibition, Messe Nagoya, which marks its 13th edition, started in 2006 as a project that inherits the principles of the Aichi Expo (environment, science and technology, international exchange). It is a "festival of inter-industry exchange" that seeks exhibitors from a wide range of fields and regions, transcending industry and business type, aiming to expand transactions between exhibitors and visitors, disseminate information, and promote inter-industry exchange. It is one of Japan's largest business exhibitions. Our company will showcase not only our main products related to adhesive processing and secondary processing samples but also development materials such as AD-sorb, soundproof materials, and phosphorescent materials at our booth. Booth number: 3D-279 We look forward to your visit.

We are currently developing a protective sheet for reinforced glass display materials that utilizes the shock-absorbing properties of AD-sorb elastomers. Since 2015, various verification activities have been conducted on the implementation of a display board "andon" in a highway tunnel, which has resulted in no damage such as cracking or shattering of the display board after implementation. As a result, the number of tunnels planned for additional implementation has increased, and we expect to complete the development of specifications that can be implemented in outdoor materials requiring higher levels of weather resistance soon. Implementation tests for soundproof glass and other materials are also scheduled to begin. Additionally, we are actively advancing the development of sheet materials that combine AD-sorb elastomers with heat-insulating and light-blocking agents, featuring various characteristics such as heat insulation, light blocking, soundproofing, vibration control, and crack prevention. We will begin implementing these materials in building window glass and other applications starting in 2018.

3rd Wearable EXPO — A Comprehensive Exhibition of Wearable Devices Utilization and Technology — Date: January 18 (Wednesday) to January 20 (Friday), 2017, 10:00 AM to 6:00 PM (until 5:00 PM on the final day) Venue: Tokyo Big Sight Organizer: Reed Exhibitions Japan Ltd.

The Nagoya Plastic Industry Exhibition is scheduled to be held from October 7 (Wednesday) to October 10 (Saturday), 2015, at Port Messe Nagoya (Nagoya International Exhibition Hall) under the theme "Innovative Plastics! Aiming for High Added Value," and our company will be exhibiting for the first time at this event. We plan to showcase a variety of development materials that cater to many fields, including adhesive and secondary processing products, as well as composite products coated with high-performance coatings from our partner companies, focusing on keywords such as "sound, heat, vibration, and shock absorption." We look forward to your visit.

The International Frontier Industry Messe 2015 is scheduled to be held on September 3rd (Thursday) and 4th (Friday) at the Kobe International Exhibition Hall, with the theme "Bringing 'Power' from Hyogo and Kobe to the Region and the World." This will be our company's first participation in the exhibition. We plan to showcase development materials that correspond to various fields, featuring keywords such as "sound, heat, vibration, and shock absorption," including high-performance coatings developed in partnership with our affiliates and composite products made with various materials. We look forward to your visit.

We would like to express our sincere gratitude for the many visitors who came to our booth at the Wearable EXPO 2015 held at Tokyo Big Sight from January 14 (Wednesday) to January 16 (Friday) this year. We received very valuable feedback and inquiries regarding the AD-sorb series of vibration-damping and shock-absorbing elastomers, as well as soundproofing and sound-absorbing materials like Sound Proof, and heat dissipation materials. Our sales team is currently working diligently to respond to these inquiries in order. We appreciate your continued support as we challenge ourselves to develop functional coatings.
