Government tenders in Japan: where they are published.
Tenders in Japan do not live at a single address. Chotatsu Portal is the reference channel, and 6 more sources, from public agencies to state companies, publish their own notices beside it. TRINTA maps 8 sources in the country.
The national channels
These are the public, national-level sources: anyone can find them in one search. They carry a large share of the notices, not all of them.

And everything that publishes beside them
Beyond the national channels, 6 more sources in Japan publish their own notices. We count them by category without naming them: the complete source map is what sets the radar apart, and it is not published.
Opening 8 pages every morning is feasible for a week, not for a commercial year. That is the cost this fragmentation imposes on every supplier that takes the market seriously.
What TRINTA does on this market
TRINTA reads these sources every day so the company does not have to. The radar is built per client: it starts from the company's real catalogue, builds a multilingual keyword profile, then scores every notice 0 to 100 against what the company actually sells, with the reasoning shown. Procedure documents are retrieved and attached, and a short scored list arrives each morning.
The same radar covers 153+ countries and 1,539 mapped official platforms, plus the multilateral lenders. A company selling in Japan rarely sells only in Japan.
