Acquired a wall ratio of 3.3 times. Protecting homes from earthquakes! Maintenance-free seismic dampers!

The Minister of Land, Infrastructure, Transport and Tourism certified seismic damper, the K-Damper, is a damping device that has achieved a wall strength ratio of 3.3 times. It employs phenolic resin technology, commonly used in automotive disc brakes, to convert seismic vibrations into frictional heat and absorb them. **Features** - Certified by the Minister of Land, Infrastructure, Transport and Tourism, achieving a wall strength ratio of 3.3 times. - By installing four units per building, it can reduce vibrations by up to 76%. *Compared to a structure equivalent to seismic grade 1. - The damping material uses phenolic resin, which consistently demonstrates excellent damping performance. - Durability is over 169 years, with no degradation in performance even after 700 cycles of repeated friction. *Based on test results for ministerial certification application. *For more details, please download the catalog or feel free to contact us.

Acquired a wall multiplier of 4 times! A seismic damper specialized for 3-story buildings!

The seismic damping device for wooden houses, the K3 Damper, is a damping device that has achieved a wall amplification factor of 4 times. It is specifically designed for three-story buildings and can be used without any issues in homes with low ceiling heights. **Features** - Achieved a wall amplification factor of 4 times through certification by the Minister of Land, Infrastructure, Transport and Tourism. - Reduces shaking caused by earthquakes by up to 81%. (The reduction rate varies depending on the floor plan and structure.) - For three-story buildings, it is recommended to install 6 units or more per building. (The number of units varies based on the total floor area.) - The phenolic resin built into the damper achieves maintenance-free performance equivalent to 169 years. (Calculated through accelerated testing.) - Maintains stable performance even after 1,000 repetitions of shaking equivalent to a major earthquake. *For more details, please download the catalog or feel free to contact us.*

We will be exhibiting at the joint company information session hosted by Mynavi on the following schedule. We will clearly explain the four core businesses of Takaya. If you are interested in "monozukuri" (manufacturing), please come to our booth!

At this exhibition, we will introduce our materials equipped with new functions and values that contribute to solving our customers' challenges. Our mid-term management plan includes "securing competitive advantage through technology leadership" as one of its basic strategies, and our engineers, who embody this strategy, will explain and propose the exhibited products in their own words. We would love to hear your feedback, so please feel free to stop by our booth.

[Speaker] Naoki Toda, Chief Economist, Management Strategy Research Office, Tokyo Electric Power Company Holdings, Inc. [Key Lecture Content] Since the 1990s, the global advancement of power system reforms has aimed for efficiency and optimization in both the operation and investment of facilities through active market competition. However, with the progress of DX/GX, the anticipated scenarios for electricity demand have led to the emergence of underinvestment issues worldwide. The IEA's report "Electricity Market Design," published last year, provides a comprehensive review of the reform situations in various countries and indicates that the underinvestment problem is a common issue across the globe. In this lecture, I will explain the current state of the underinvestment issue and potential responses from a business system perspective, referencing the IEA report and others. [Lecture Items] 1. Background of power system reforms and the underinvestment issue 2. About IEA "Electricity Market Design" 3. Reflecting on the thoughts of Akihiro Sawa on the 10th anniversary of his passing 4. Possible solutions to the Tenor Gap issue 5. Outlook for Japan's power system 6. Q&A / Business card exchange

[Instructor] Shinichiro Takiguchi, Senior Specialist, Innovation Strategy Center, Japan Research Institute, Inc. [Key Lecture Content] With the increase in renewable energy, the introduction of energy storage systems has progressed in two forms: renewable energy co-located systems to adjust power generation fluctuations, and demand co-located systems to secure electricity during grid outages. However, the landscape is changing significantly. The "Supply and Demand Adjustment Market" has been established by OCTTO (Organization for Cross-regional Coordination of Transmission Operators), and particularly due to the continued high pricing agreements in the short-term response market (primary adjustment power responding within 10 seconds), there have been numerous cases where battery storage profits are secured through market transactions. In the grid energy storage business, two capabilities are required: "trading power" and "financial power." This lecture will explain the business structure and key points of profitability. Additionally, based on this business structure, we will classify the companies entering the grid energy storage business and organize the market structure of this sector. As this business is influenced by regulatory trends, we will also discuss regulatory outlooks. Finally, we will talk about future prospects.

[Lecturer] Professor Yoshiharu Nishimura, Senior Researcher, Kansai Electric Power Co., Inc. Graduate School of Engineering, Osaka University, Business Engineering Program [Key Lecture Content] The examination of the next-generation power infrastructure conducted in 2025 has entered the implementation phase, including amendments to the Electricity Business Act, towards a new power policy standard (a sustainable framework by responsible players) in 2026. This lecture will outline the content and related policy adjustments for businesses involving renewable energy and storage batteries, and consider the correct business concepts, necessary timelines, and how to create business models moving forward. [Lecture Items] 1. What is the 2026 Next-Generation Power Infrastructure Reconstruction? 2. Renewable Energy and Decarbonization Policies and Issues with Chinese Products 3. The Latest Status of Storage Batteries and the Timeline and Vision for DER Business 4. Q&A / Business Card Exchange
