I'd been reading about kogei (the Japanese word for traditional crafts) and couldn't find a good English-language reference that treated it as more than a gift-shop tourism page. The 236 government-designated crafts have a thousand years of history behind them, specific regional origins, and named artisans. Most of them have zero searchable presence outside Japanese-language sources.
So I built the reference I wanted. The structure was the interesting part: organise by region, by category, by technique, by artisan, without it turning into a wiki or a marketplace. It's deliberately a reference site, not a store.
