Smart Delivery Lock System Surpasses 10,000 Deployments in Kantō Region

Lainaf Inc., headquartered in Bunkyo, Tokyo, proudly announces that its innovative "Smart Delivery" system has exceeded 10,000 implementations in the Kantō region, which includes Tokyo, Kanagawa, Saitama, Chiba, Ibaraki, Gunma, and Tochigi. The logistics industry is undergoing significant transformation, especially following the Ministry of Land, Infrastructure, Transport and Tourism's declaration to integrate "delivery drop service" into standard delivery practices. Lainaf aims to significantly expand its system across the entire Kantō area in response to emerging challenges in this sector.

A National Trend

With over 19,000 installations nationwide, the Smart Delivery service utilizes digital keys to ensure safe deliveries even in auto-lock apartment buildings. This service contributes to reducing the need for redelivery and improves the convenience of residents, while also streamlining management duties by alleviating delivery-related issues.

Background and Future Prospects

As the logistics sector grapples with labor shortages and rising CO₂ emissions, the importance of initiatives aimed at cutting redelivery has escalated. Factors unique to urban living conditions and household compositions in the Kantō area underlie the widespread adoption of the Smart Delivery service, particularly the high percentage of auto-lock buildings and a noteworthy increase in single-person households in Tokyo. The growing demand for reliable delivery options for residents who are often away during the day highlights the need for such an efficient system. As a result, the Smart Delivery service is gaining prominence, offering both safety and efficiency.

How It Works

The service employs the "NinjaEntrance" smart lock to digitize access to the shared entrances of auto-lock apartments, allowing authorized delivery personnel to unlock doors and place packages in specified locations. All unlocking activities are logged, ensuring security while eliminating the financial burden on building managers, landlords, and management associations for installation costs. As of January 2026, over 19,000 properties have benefited from this advancement.
