Japan Layman is a newsletter that examines Japanese engineering and industrial projects in depth, such as car-parts makers entering data-centre cooling, robots for gas pipe inspection, and rocket turbopump seals. Each issue combines reporting from company filings and briefings with analysis of the gaps between corporate claims and commercial reality.
