Two of the free services we run at LoreaTec Labs are aimed squarely at companies doing business with, or in, Japan.
Japan Tenders — government procurement, in English
Japan Tenders collects public-sector tenders and procurement notices from across Japan and translates them into English every day. You can search for free and set up email alerts, so foreign suppliers can follow Japanese government opportunities without reading through each portal in Japanese.
BizSearch — check any Japanese company
BizSearch lets you look up any Japanese company by its corporate (T-)number: registered details, licenses, qualified-invoice registration, procurement history, and a set of import and trade tools. It is a fast way to run due diligence on a supplier or partner in Japan.
Both are free to use. Explore them, and the rest of our tools, at LoreaTec Labs.
