Seino Group Unveils the Future of Logistics with Nano-Stream

On June 16, 2026, Seino Group’s logistics company, Chikuta Express Co., Ltd., held an event at its second logistics center in Chiba City to announce the launch of its first next-generation automated warehouse, "Nano-Stream". This groundbreaking system promises to revolutionize the logistics industry by significantly boosting storage efficiency and streamlining operational processes.

The Launch Event

The automated warehouse initiation ceremony showcased the Nano-Stream technology, produced in collaboration with ROMS Co., Ltd. Following an impressive live demonstration of the automated transport capabilities and three-dimensional storage system, the event drew significant media attention, with various representatives sharing insights on the technology and its implications for future logistics strategies.

What is Nano-Stream?

The Nano-Stream is an advanced automated storage system that incorporates high-density storage and automatic transportation solutions. By transitioning to a three-dimensional storage model, it is set to achieve approximately three times the storage efficiency of conventional methods. Moreover, the deployment of the Nano-Stream is forecasted to reduce the required workforce by 25%, enhance order picking and delivery processes, and respond more effectively to the growing demand for small parcel and e-commerce deliveries.

Context of Implementation

The logistics sector is currently grappling with two major challenges: an increasing demand for small parcels resulting from e-commerce growth, and a shortage of workforce. In light of these challenges, both operational efficiency and a reduction in labor requirements are critical priorities. Seino Group’s medium-term management plan from 2026 to 2029 prioritizes the strengthening of logistics and delivery functions focused on small parcels, placing the introduction of the automated warehouse at the core of this strategy. By continuing to enhance its capacity to accommodate the anticipated growth in small parcels, Seino Group aims to establish a sustainable last-mile logistics framework.

Impact of Implementation

The introduction of the Nano-Stream is set to fundamentally alter logistics efficiency. The technology addresses the current limitations in traditional flat operations, which struggle with quality, efficiency, and cost. According to the president of Chikuta Express, Mr. Hidetsugu Kawai, the transition to Nano-Stream is a proactive solution to navigating challenges such as workforce acquisition and rising costs, particularly fitting for their operational model. The swift timeline from decision-making to installation also received positive remarks.

In a statement, Mr. Yosuke Maeno, CEO of ROMS, expressed honor in partnering with Seino Group for this project. He emphasized that the true value of their machinery lies in its everyday utility for customers, fostering a collaborative relationship where they continually refine and enhance operational performance of the Nano-Stream to fully meet their needs.
