If you're building anything for Japanese users and wondering why high-converting sites look "cluttered" by Western standards, this explains the actual principles. It covers the anshin concept (reassurance through visible information), bento layouts, trust signals like staff photos and shipping badges, and why hiding details behind "learn more" buttons kills conversions. Includes real CSS patterns, typography rules for Japanese fonts, and specifics like how Rakuten-style product cards differ from Amazon. Most useful when you're adapting a Western design for Japan or building e-commerce, but applies to SaaS and B2B too. The cultural context section on why information density works is worth reading even if you're just curious.
