Zukan series
Free databases that turn data published by Japan's government, local authorities and companies into something anyone can explore. Operated by CLT Godo Kaisha, the company behind CLT Trust.
Each site is a "zukan" (an illustrated guide) for one theme. Pages about the same company, person or place link to each other across the sites, so you can go from a company's results to its major shareholders, or from a town's finances to its vacant houses and salons.
The sites
Kessan Zukan
Financial results of Japanese companies, listed and private, in one place — compare any company with its peers.
Shisan Zukan
The wealth, estimated income and dividends of founders, executives and major shareholders of listed companies.
Zaisei Zukan
The finances of every Japanese municipality and prefecture, with ten-year trends and peer comparisons.
Seiji Zukan
Income and spending of parties, political groups and Diet members, and who donated to them (Japanese only).
Haikou Zukan
Closed schools and vacant houses across Japan, with the total cost to start — including repairs and renovation by use.
Salon Zukan
Hair salons, barbershops, nail and lash salons in Japan and the US — new openings appear quickly.
Shigoto Zukan
Pay, outlook and AI risk for each occupation, with data from Japan and the US.
Kantei Zukan
Take a photo and AI identifies the item and estimates its price today and in 1, 3 and 5 years (Japanese only).
Access Zukan
Monthly traffic rankings of websites in Japan and worldwide, and a dashboard that combines GA4, Search Console and AdSense (Japanese only).
Figures show the number of entries on each site as of October 2026.
