## The national channels

- Chotatsu Portal (https://www.p-portal.go.jp/): Japan's unified government procurement system.
- Government Procurement Information (https://information1.gov-procurement.go.jp/en/?L=en&tc=1): The official government procurement information site.

## The rest

- 2 state-owned enterprises publishing their own notices
- 2 regional, state and municipal buyers with their own portals
- 1 ministries with their own tender sections
- 1 other public buyers publishing their own notices

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.

TRINTA reads Japan's official sources every day, 8 mapped, 3 read by a dedicated connector. The radar is built per client: it starts from the company's real catalogue, builds a multilingual keyword profile, scores every notice 0 to 100 for fit with the reasoning shown, and attaches the procedure documents. A short scored digest arrives each morning. The same radar covers 153+ countries, so a company selling in Japan can watch neighbouring markets with the same profile.
