Autoform - Autofill Japanese Forms

About

Living in Japan, filling out forms can feel like a never-ending hassle—hospital appointments, restaurant reservations, administrative applications, membership registrations… Every time, you have to re-enter your name, pronunciation, address, phone number, and more. **Autoform** turns all of that into a single click.

Save your personal information once, then click the toolbar icon on any Japanese form. The extension automatically detects the input fields on the page and fills in only the items required for that form.

■ **Automatically handles the quirks of Japanese forms**

・**Name:** Save kanji, furigana, and romanized versions separately. Even if only the “last name” field is labeled, Autoform can infer the “first name” field automatically.
・**Furigana:** Automatically converts to full-width katakana. Hiragana fields are filled with hiragana, and half-width kana fields are also supported when specified.
・**Date of birth:** Automatically converts Gregorian calendar dates into Japanese era dates — Showa, Heisei, Reiwa — and can also fill era dropdown menus.
・**Address:** Automatically splits and fills prefecture, city/ward/town/village, street address, and building name.
・**Phone number & postal code:** Automatically splits them into multiple half-width fields, such as 090 / 1234 / 5678.
・**Company name pronunciation:** Correctly fills company-name readings without confusing them with personal names.

■ **Privacy first**

・All personal information is stored only in your local browser using `chrome.storage.local`; it is never sent externally.
・The entire form-filling process runs offline. No servers, no tracking.
・By default, it only acts on the current page when you click the toolbar icon.

Ideal for common Japanese online forms such as hospital and clinic appointments, restaurant reservations, administrative applications, and membership registrations.

Supports Chrome and Chromium-based browsers, including Edge. Free to use.

在日本生活，填表是件没完没了的麻烦事——预约医院、订餐厅、各种行政申请、会员注册，每次都要重新输入姓名、读音、地址、电话…… Autoform 帮你把这一切变成「点一下」。

个人信息只需预存一次，之后在任何日本表单上点击工具栏图标，扩展会自动识别页面上的输入框，只填这张表需要的项目。

■ 日式表单特有的坑，全自动处理
・姓名：漢字 / フリガナ / 罗马字 分开保存；就算只有「姓」有标签，也能自动推断「名」
・フリガナ：自动转成全角片假名（ふりがな栏自动用平假名，半角カナ指定也支持）
・生年月日：西暦自动换算成和暦（昭和 / 平成 / 令和），元号下拉也能填
・地址：自动拆分填入 都道府県 / 市区町村 / 番地 / 建物名
・电话・邮编：自动分成多个框（半角），如 090 / 1234 / 5678
・公司名的读音也能正确填入，不会和人名搞混

■ 隐私优先
・所有个人信息只保存在本机浏览器内（chrome.storage.local），绝不外传
・填表全程离线运行，没有服务器、没有追踪
・默认只在你点击工具栏图标时，作用于当前页面
