Exhibited at the 6th Smart City Expo within Local Government & Public Week; Unveiled Official Mascot 'I-neck-n'

I-neck Corporation, which operates environmental solution businesses related to electricity, exhibited at the '6th Smart City Expo' within Local Government & Public Week, held at Tokyo Big Sight from May 13 to May 15, 2026.

The official mascot 'I-neck-n' debuted and welcomed guests.

Exhibition Overview

Under the theme of 'Towards Carbon Neutrality—Can we make it by 2030?', our booth presented environmental solutions that simultaneously achieve decarbonization and strengthen disaster resilience for public facilities.

With a background of over 28,000 energy-saving and renewable energy site surveys and designs for public facilities nationwide, we proposed a combination of a 'design-build method'—which handles everything from design to construction and maintenance—and a 'leasing method' that reduces initial investment. This proposal aims to contribute to achieving the government's 2030 action plan within limited time and budgets.

Four Exhibition Themes

1. LED Conversion Solutions for Public Facilities
We support the process from budget request to bidding and construction with free diagnostics. By utilizing the 'design-build method' and leasing, we achieve shorter lead times and eliminate the need for new budget allocations. In a model assuming a city with a population of 380,000 (405 public facilities), the projected impact includes a 72% reduction in CO₂ emissions, a 3.6 billion yen reduction in utility costs, and a 300 million yen reduction in maintenance costs.

2. 'Self-Sufficient Energy Shelter' Concept
While air conditioning implementation for resilience is progressing, we started from the question, 'Does a shelter function with just air conditioning?' and proposed 'Self-Sufficient Energy Shelters' capable of powering lighting, mobile charging, water supply, and information communications. We explained concrete operational images for normal, disaster, and power outage scenarios using power supply simulations combining photovoltaic (PV) power and storage batteries.

3. Municipal Case Study—'Zero Carbon City Gamagori' Project
We introduced the decarbonization project in Gamagori City, Aichi Prefecture, which has declared a 2050 carbon neutral goal. The project involves installing solar panels at approximately 50 facilities and converting about 150 lights to LED. We showcased the scheme for city-wide decarbonization and the design philosophy of achieving both decarbonization and resilience.

4. Industry-Government-Academia Collaboration with Kanazawa University's 'Co-Creation Planning Office'
Since 2025, we have participated in the 'Co-Creation Planning Office' newly established by Kanazawa University's Future Knowledge Demonstration Center. We are promoting an 'off-grid shelter concept' that balances decarbonization and disaster prevention as a joint research theme. We presented this effort to realize practical off-grid shelters optimized for local characteristics by combining academic knowledge, municipal regional data, and our social implementation power.

Official Mascot 'I-neck-n' Debut

The official mascot 'I-neck-n' greeted guests for the first time at our booth. We also screened an image movie condensing our philosophy and proposal stance. Decarbonizing public facilities is an urgent issue, and the power that supports shelter functions during disasters is a lifeline for local life. Simultaneously achieving decarbonization and disaster prevention is work to pass on Japan's seasons and local lifestyles to the future, reflecting our determination to walk together with 1,718 municipalities nationwide. We conveyed this message through the video.
