Bridge plugin enabling communication between the Japanese government's One-Stop Automobile Ownership Procedures web service (oss.mlit.go.jp) and a local native messaging application for document processing and submission

Facilitates Japanese automobile ownership-related government procedures (vehicle registration, insurance, tax filings) by enabling the government web portal to interact with local native applications for digital signing, document processing, and secure data exchange that cannot be done through a standard browser alone

User accesses oss.mlit.go.jp government portal → authenticates with government credentials → the web page invokes plugin methods via postMessage → content script relays to background service worker → background connects to native messaging host (jp.go.mlit.oss.term.addon) → native app processes request (likely digital signing/certificate operations) → results flow back through the same chain to the web page

Target users: Japanese citizens and businesses processing automobile ownership procedures / Users of the MLIT One-Stop Service portal (oss.mlit.go.jp)

Chrome Web Store detail was unavailable (fetch error), so no store metadata could be used for verification
Cannot inspect the native messaging host application (jp.go.mlit.oss.term.addon) which may have its own requirements
The specific government authentication method cannot be confirmed from extension source alone

Monetization

No paid features detected

This is a Japanese government browser extension for automobile ownership procedures. There is no evidence of any paid features, billing, subscriptions, or payment processing anywhere in the codebase. All keyword hits for 'pro' are false positives matching JavaScript variable names like 'portProp' and 'properties'. Government services in Japan are typically free or charge only standard administrative fees at the destination, not through the extension.

Confidence: 95
Payment platform: --
Source: AI / Medium
Login required: Yes
Reason: The extension reads sessionId and CSRF tokens from meta tags on the destination service (oss.mlit.go.jp), which is a Japanese government portal for automobile ownership procedures. Users must be authenticated with the government service to use the core workflow. The extension itself does not implement login UI; authentication is handled by the destination government web application (likely requiring My Number Card or similar government credentials).
