AI 产品解读Chrome extension that bridges the Japanese e-Tax web application with a native Windows application and IC card reader for My Number card authentication and digital signing
Enables Japanese taxpayers to log into the government's e-Tax electronic tax filing system and digitally sign tax filings/applications using their My Number card and IC card reader through Chrome, which otherwise cannot directly access hardware card readers
User installs the extension and a companion native Windows app. When visiting e-Tax websites (login.e-tax.nta.go.jp, keisan.nta.go.jp, etc.), the content script injects hidden elements for communication. The web page dispatches custom events (NtaChromeLaunch) which the content script relays to the background script, which forwards messages to the native app via native messaging. The native app interfaces with the IC card reader to read the My Number card, perform authentication, and return signed data back through the chain.

- 目标用户
- Japanese individual taxpayers filing taxes electronically via e-Tax / Japanese tax professionals and accountants / Businesses using e-Tax for corporate tax filings / Users with My Number cards and IC card readers
- Chrome Web Store detail was unavailable (API error), so no store description or rating info could be cross-referenced
- Cannot verify the native Windows companion app (nta.chrome.ext) as it is distributed separately by the National Tax Agency
- Cannot confirm whether the extension works without the native companion app installed

- The extension is a bridge to Japan's e-Tax system (login.e-tax.nta.go.jp and related domains). Users must log in to e-Tax using a physical My Number card (マイナンバーカード) and IC card reader. The extension itself has no login UI or account system—it facilitates the connection between the e-Tax web app and a native Windows application that reads the card. The login is required at the destination service (e-Tax) to use the extension's core workflow.
理解不能
何年も続けているが高齢者には理解が難しい。努力して取り組む。
説明も不十分、何とかやっても全く繋がらない。 何のためにあるのこれ。
why did the japanese government always roll out useless, difficult to use app/extension and complicated procedures?! is the country lack of IT specialist? We are just trying to log into etax to make an application! how sophisticated can it be?! After asking AI, the tackle to this problem is by setting the default language of chrome to Japanese! because it is still using the old Shift-JIS but not the worldwide UTF-8 code. brilliant!
毎年、繋がらなかったりして、最低のソフトだ。
出来たら星０個差し上げました。なんでJavaScriptなんですか？メニューに何も表示されないんですけど。ただ青色申請したいだけなのに。はっきり言います、時間と労力の無駄です。要りません。半強制的にマイナカードを普及させようとマイナポータル使わない人の申告をわざと難しくしてるの見えてます。セキュリティ目的でWindowsを強制して中途半端なウェブ版を開発するくらいならいっそ、申請用のソフトウェア作るべきです。
