A New Habit for Preparing for 'Extreme Heat Days' Over 40°C: Remote Air Conditioning Control Before Returning Home

Nippon PC Service Co., Ltd. (Headquarters: Suita City, Osaka Prefecture; President and CEO: Nobuyuki Ie; Securities Code: 6025; hereinafter "the Company"), a provider of digital infrastructure setup, repair, and troubleshooting services, will strengthen its support system in preparation for the anticipated record-breaking "extreme heat" of summer 2026. The Company will promote home environments resilient to extreme heat by leveraging home IoT devices to prevent heatstroke. With the official definition of "extreme heat days"—days with maximum temperatures exceeding 40°C—heatwaves are no longer temporary anomalies but a persistent risk in daily life. Especially for elderly individuals at home, children, or pets left unattended, rising indoor temperatures pose life-threatening risks, making household-level preparedness essential.

A variety of device models are now available for different use cases.

[Background]

On April 17, 2026, the Japan Meteorological Agency announced a new term, "extreme heat day," for days with maximum temperatures of 40°C or higher. "Severe heat days" (35°C or higher) and "extreme heat days" are becoming the new normal for Japanese summers. As high temperatures increasingly affect health, home IoT devices for heat mitigation are rapidly gaining popularity. While smartphones can now connect to a wide range of devices with diverse functionalities, many households face confusion due to complicated operations and varying setup procedures across manufacturers, leading to underutilization. The Company leverages its nationwide network of 380 service points to eliminate these barriers—such as "not knowing which device suits my home," "it seems too difficult for me," or "I don’t understand how to use it"—and supports heatstroke prevention during extreme heat.

"Cool the home before returning, stay safe even when away"—one smartphone can resolve various anxieties and concerns.

One smartphone can solve multiple problems and worries.

Actual feedback from users

Feedback from a household (installed in 2026, male, 50s)

"I can control appliances by voice, and managing all remotes in one place has made my room much tidier."

Feedback from a chiropractic clinic (small business, installed in 2026)

"Being able to turn on the air conditioner remotely when appointments are booked saves energy and is very convenient! Previously, I had to arrive early to adjust the room temperature, so now I have more preparation time."

Even after installation, technical issues or difficulties with home IoT systems can be more than just inconvenient—especially for elderly households unfamiliar with digital operations or dual-income families who leave children at home early. Such issues directly translate into life-threatening risks like heatstroke. To address this, the Company fully utilizes its nationwide service network to offer a comprehensive package including device selection, setup, configuration, instruction, and post-installation troubleshooting.

Ahead of the approaching extreme heat season, the Company is enhancing its support to ensure that the benefits of home IoT reach those who need them most. Smart home technology will be key to reducing household burdens and ensuring safety in Japan’s rapidly aging society. However, this depends on the fundamental trust that these systems are "reliably usable at all times." As an independent provider unaffiliated with any single manufacturer, the Company supports connectivity across all devices, ensuring that home IoT is not "set up and forgotten," but rather a source of continuous peace of mind.

Additionally, coinciding with the renovation of the DigiHo store in Esaka, Osaka, a free "Smart Home" showroom will open on June 17 (Wednesday), offering the public a hands-on opportunity to experience extreme heat countermeasures up close.

Experience convenient devices firsthand at the showroom!

The DigiHo store in Esaka, Osaka, now features a free showroom where customers can experience IoT devices in person. Consultations for home IoT adoption are also available during on-site support visits in other regions.
