We exhibited our Solar House at the multifunctional disaster‑prevention community hub Friends.For the first time, we enabled a Snoezelen experience inside the Solar House using its internal power system.Many children participated on the day of the event, and some enjoyed it so much that they came back repeatedly.This experience reminded us of the importance of providing spaces where children can relax and momentarily forget the hardships they may face during disasters.What is Snoezelen?Snoezelen is a sensory‑stimulation environment that uses light, sound, and fragrance.In a darkened space illuminated by blacklight, participants can relax in a gentle, dreamlike atmosphere.It is widely used in dementia care and developmental support.https://www.snoezelen.jp/snoezelen

On Friday, October 10th, as part of the pilot project currently being advanced by Daiwa Tech, KPMG Ukraine held a meeting in Japan with the participating organizations. In conjunction with this, Daiwa Tech provided an overview of its activities in Japan, including discussions, and arranged a tour of the production site.

Daiwa Tech has installed ten solar system houses at the training grounds of the Japan Ground Self-Defense Force’s 8th Division (Chinzei Mobile Division).Following connections made with Self-Defense Force personnel at last year’s Kumamoto exhibition, the system was adopted based on its potential effectiveness for restoring combat readiness during training (including heatstroke countermeasures).We sincerely hope this contributes to enabling all those involved in national defense to participate in training in optimal physical condition.
