On April 17, 2026, Japan’s Ministry of Economy, Trade and Industry (METI) published the “Entrepreneur-Led Carve-Out Practice Guidance Guidebook (Why Edition / How Edition).　

“Tsubame BHB Co., Ltd. — established in 2017 through a carve-out of Ajinomoto Co., Inc.’s small-scale distributed ammonia production technology development team, with investment from Universal Materials Incubator Co., Ltd. (UMI) — has been featured as a leading carve-out case study from a major corporation in this guidebook. Tsubame BHB is engaged in the development of compact plants for realizing Japan’s first onsite ammonia production system.

The guidebook was compiled by NEDO as a supplementary resource to the “Entrepreneur-Led Carve-Out Practice Guidance” published in April 2024, designed to support more practical application of that guidance.

The guidebook consists of two parts. Part 1: The “Why Edition” is aimed at corporate management and middle managers, explaining the significance of carve-outs and providing a business decision-making framework for building internal consensus. Part 2: The “How Edition” is intended for entrepreneurs (intrapreneurs) pursuing carve-outs, offering a systematic overview of practical challenges in areas such as intellectual property, capital policy, and human resources, along with approaches for navigating internal coordination.

We will continue to promote the social implementation of technologies and expertise developed within our organization, and remain committed to driving open innovation and new business creation.
