The RanTEC Backpack: A New Era in Backpack Evolution

In a groundbreaking move, Kyowa Co., Ltd., a leading manufacturer of school bags, is set to launch their next-generation backpack, "RanTEC," on November 11, 2025. This innovative product promises to redefine how we perceive backpacks by incorporating technology traditionally reserved for children's bags, particularly the iconic "backkan" feature used in randoseru (Japanese school bags).

The Origin of RanTEC

The idea for RanTEC emerged from a casual discussion within the company, leading to the question: “Can we combine the best aspects of randoseru and adult backpacks?” This sparked a journey of innovation that ultimately resulted in the RanTEC. Initial prototypes showcased the potential of integrating crucial elements from children’s bags into adult-sized backpacks, paving the way for iterative improvements over several years.

Key Innovations

Kyowa is proud to highlight three main advancements that make the RanTEC stand out:

1. Unique Technology: The RanTEC incorporates the core technology of the backkan, offering a distinctive fit for adults.
2. Comfortable Load Distribution: Thanks to the patent-pending "RanTEC System," the bag effectively distributes weight across the shoulders, back, and waist, making it feel lighter.
3. 77 Years of Expertise: With decades of experience in crafting school bags, Kyowa's commitment to quality ensures that the RanTEC is both reliable and innovative.

What Does RanTEC Mean?

The name "RanTEC" combines "randoseru" and "technology," reflecting its roots in traditional craftsmanship while simultaneously embracing modern design and functionality. The logo features an "R," symbolizing the children carrying randoseru, reminding users of the essence of this innovative product.

Five Features for Unmatched Comfort

The RanTEC showcases five distinctive functionalities derived from randoseru tradition:

• - Backkan Function: A movable mechanism at the base of the straps allows for optimized fit across different body types and clothing.
• - Chest Support Structure: This design minimizes gaps, allowing the backpack to stay high on the back for better stability and comfort.
• - Backboard Structure: Applied posture support technology ensures weight is distributed efficiently, promoting good posture.
• - 3D Cushion Foam: Thoughtfully designed cushioning envelops the back while enhancing breathability, preventing discomfort during warmer months.
• - Chest Support Function: This feature stabilizes the straps and minimizes movement, ensuring enhanced stability during active use.

Exceptional Lightweight Design

Weighing only about 1,100 grams, similar to a liter of bottled water, the RanTEC's lightweight character coupled with the RanTEC System provides an experience of lightness that's rare in modern backpacks.

Elegant Aesthetic

Designed for both business and casual settings, the RanTEC features a sophisticated silhouette while retaining the durability characteristic of traditional randoseru. The bag's curves and high-quality materials offer a versatile look suitable for various occasions.
