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.
税の申告をするだけなのに妙なソフトをいくつもインストールさせられ、途中でひっかかりまくる。UXがなっていない。デジタル庁はなにをやっているのか？
ひらかない
笑うしかできません。
最低の拡張。e-Taxを利用するのに必要だから入れろとのことで入れたにも関わらず、あいも変わらず拡張機能が入っていないからe-Taxの機能が使えません、等と言われる。再起動しても駄目。どうしようもない。民間なら倒産しているレベルのクオリティ。
税金を払わせたくないのかと思うほどのわずらわしさ お役所仕事の大馬鹿さ加減が露呈してる。
Complete junk. Either shows a blank screen or 読み込み中. It doesn't matter if you've installed all the extensions and apps they require. Having this as a requirement to properly get documents to file your taxes is insane.
CHANGE CHROME TO JAPANESE
何十回もマイナンバーカードでログインさせるくせに、目的までたどり着けない、 わざと手続きを面倒くさくして税金控除を諦めさせようとしている。 鬼畜にも劣るアプリです。
最低のアプリ。老人には全く使えません
I fully agree with Neill Walker, Steph, Chao Gu, Michael Mauer, Anan Mikami, Ryohei Enomoto, David Oppenheimer and Lee Fischer. This is an example how to waste tax payer's money. I am sure the development was outsourced to a bidder, one of the JTC(Japanese Traditional Companies). The least thing the National Tax Agency can do is to instruct the contractor to fix and improve the software. It is a pity to see that people take time to give valuable feeback since Feb 2022 and nothing happened for more than 4 years...
