Notice of participation in the Regional Public EXPO (Municipal and Public Week 2006) exhibition from May 13 (Wednesday) to May 15 (Friday), 2026.

Exhibition at the Earthquake Disaster Prevention Technology Show! Remote operation and monitoring of operational status are possible. By unlocking/locking the box with earthquake detection, keys can be retrieved even in the absence of the custodian.

We would like to introduce the "Multi Unlock Box" handled by Yamashoko Electric Manufacturing. In the event of a disaster, the box can be unlocked/locked remotely. The locking time and sensitivity to seismic activity can be adjusted in four levels, and it operates on solar power with a rechargeable battery, eliminating the need for an external power source. Additionally, with a dedicated web application, it is possible to monitor the operational status of the box, such as the unlocking state and door opening/closing status, on a map. 【Features】 <Main Functions> ■ Unlock/lock the box based on earthquake detection ■ Earthquake detection function uses XYZ 3-axis synthesis ■ No external power source needed with solar power and rechargeable battery ■ Locking time and sensitivity to seismic activity can be adjusted in four levels 【Exhibition Information】 Exhibition: Disaster Prevention Technology Exhibition Dates: February 8 (Thursday) and 9 (Friday), 2024 Venue: Pacifico Yokohama, Hall D Booth Number: 307 *For more details, please refer to the PDF document or feel free to contact us.

The seismic sensor detects tremors equivalent to seismic intensity 5 weak to 6 weak! The handle lock is automatically unlocked.

The "Automatic Unlocking Box for Earthquakes" is a box that allows for quick access to the keys at the entrance of a shelter even when the key holder is absent during an earthquake. Earthquake detection is based on the composite acceleration values of the X, Y, and Z axes. The time setting for automatic locking after automatic unlocking can be set to four levels: 6 hours, 12 hours, 24 hours, or infinite (locking by pressing the reset switch). 【Features】 ■ Earthquake detection is based on composite acceleration values of the X, Y, and Z axes. ■ Earthquake detection levels: Four settings are possible within the range of seismic intensity 5 weak to 6 weak. ■ The time setting for automatic locking after automatic unlocking can be set to four levels: 6 hours, 12 hours, 24 hours, or infinite (locking by pressing the reset switch). ■ Dimensions: Width 110 × Height 210 × Depth 100 ■ Weight: Approximately 1.5 kg *For more details, please refer to the PDF document or feel free to contact us.

• Disaster prevention supplies

Detects earthquake tremors to prevent items on shelves from falling! A wireless type that can be retrofitted to existing steel racks.

We would like to introduce the "Falling Object Prevention Device" developed independently by Yamashoko Electric, which uses a drop sensor. When the seismic sensor detects the shaking of an earthquake, it transmits an operation signal via 920MHz band wireless communication. The receiving sub-device activates the falling object prevention device, protecting stored items with a protective bar and bellows. Please feel free to contact us when you need assistance. 【Features】 ■ One seismic sensor can support multiple devices ■ The detected earthquake acceleration can be set according to the purpose *For more details, please download the PDF or feel free to contact us.

Solar power generation is entering a scalable era— Have you given up on introducing solar power generation, or are you thinking, "I want to implement it more smoothly"? "Installation constraints," "enormous costs," "prolonged procedures"... By breaking through the "grid connection barriers" that hinder such introductions, you can start with what you need and expand your facilities flexibly as your business grows. The next-generation "distributed power source = off-grid system" makes such "scalable" solar power generation a reality. In this webinar, we will thoroughly explain the mechanism of "non-grid-connected self-consumption" that is not bound by existing frameworks, and present new options and the latest case studies to solve management challenges. We invite everyone considering the introduction of solar power generation to participate!

Tokyo Big Sight (West Hall 1-2) Booth Number: G13-31 Event Dates: May 13 (Wed) - 15 (Fri), 2026 Opening Hours: 10:00 AM - 5:00 PM We will be showcasing our earthquake preparedness products. Live demonstrations of the actual products will be conducted, so please come and take a look if you're interested. We look forward to your visit.

We will provide a clear explanation in a Q&A format based on the inquiries and examples received so far regarding "Headless CMS," addressing the questions that web managers truly want to know. Using the Japanese-made headless CMS "microCMS" as a subject, we will organize the key points for implementation and operation. ■Recommended for: - Public relations, marketing, digital promotion, and information systems personnel considering the introduction or replacement of a CMS. - Those interested in headless CMS but lacking a clear image of actual operations. - Individuals who want to understand the differences from traditional CMS and specific points to consider during implementation. - Those experiencing challenges with updating their company website, security, display speed, and operational load. *Please refrain from applying if you are from a competing company or an individual in the same industry. ■Agenda 1. Specifics of Headless CMS: Demo & Case Studies 2. Q&A Explanation: Utilizing Headless CMS for Corporate Websites 3. Introduction of MLC "Headless CMS Package" 4. Q&A Session *Please note that the contents of the above agenda may change without prior notice. Thank you for your understanding.

This is the 8th edition of the exhibition, which has become an internationally diverse event with many overseas companies participating. This year, we will only be exhibiting in indoor booths, but we have significantly expanded the size of our booths and will welcome everyone with more comprehensive display content. We will be co-exhibiting again this year with Great Star Japan Co., Ltd. 【Exhibited Products】 iDigTouch2D iDigConnect2D iDigConnect3D 【Highlights】 New Product "iDigConnect2D" Our highlight this time is the new product "iDigConnect2D." While Touch2D is a model that allows for easy implementation of 2D construction, Connect2D is a next-generation model with excellent expandability. By adding a GNSS antenna, it can be upgraded to 3D machine guidance in the future, allowing for a smooth transition from 2D to ICT construction. It also supports a swing boom mechanism, enabling accurate height display even when the boom is swung. It maintains high precision even in narrow sites and complex construction. 【Booth Number】 02-11 (Exhibition Hall 1)

We are pleased to announce that Hoshin will be making its first exhibition at the "Hokkaido Civil Engineering and Architecture Future Technology Exhibition"! We will be exhibiting with two booths: the Hoshin booth and the iDig booth. The iDig booth will be a joint exhibition with Great Star Japan Co., Ltd. We will showcase a wide range of content, from safety measures on site to the latest technologies, so please come and visit us! <Exhibition Booths> - Hoshin Booth: 2 sections - iDig Booth: 1 section (Mirai Collection 2026)
