JOHNAN has released a video that clearly explains the implementation technology for stretchable films, which are expected to be utilized in wearable devices and medical equipment. In the video, you can see how the film, which has excellent elasticity, stretches and contracts. Please check our high technological capabilities and the flexible characteristics that are useful for product development. We hope this will help you generate new ideas in product development. ▼You can watch the video here [Link to the implementation page for stretchable films] https://www.johnan.com/dms/mounting/filmdevic/stretchable/

Japan's climate is characterized by high temperatures and humidity, and particularly after typhoons and heavy rains, the conditions can be harsh for homes. It's not just the roofs and exterior walls that are affected by rain and wind. The area beneath the floor is actually the most susceptible and often overlooked point. This time, we will explain the "checkpoints for under the floor" that should be confirmed after a typhoon or heavy rain, the "responses" if abnormalities are found, and measures for preventing recurrence.

As part of the "Hometown Ibara Future Creation Human Resource Development Project," we welcomed local elementary and middle school students to the special summer program "Ibara Job Exploration Tour 2025," a collaboration between the Ibara City Chamber of Commerce and the Corporate Branding Committee. We conducted a presentation that clearly and enjoyably introduced how our technology supports society, allowing the children to learn about the appeal of manufacturing and the significance of working while interacting with actual devices and products. Through this initiative, we hope to deepen our connection with the community and nurture the curiosity of the children who will carry the future. We sincerely thank everyone who participated, as well as all those involved in planning and organizing the event.
