## Description

**Putting a form on your site isn’t the hard part anymore. With a popular free plugin,
anyone can stand one up in minutes. The real work comes after that — getting it 
to a state where it actually runs well on a Japanese-language site.**

A furigana (reading) field, postal-code-to-address auto-fill, a confirmation screen
before sending, a thank-you email to the sender, spam protection — the things a 
Japanese-site form obviously needs aren’t there by default in the usual plugins.
You patch the gaps with add-ons or a second plugin, look up mail-merge tags, and
sometimes edit HTML. Every field you add stacks on more setup. And the moment you
reach for a confirmation screen or more advanced features, you often run into a 
monthly or yearly charge.

Probono Form Basic exists to remove all of that “work that comes after putting up
the form.” It builds in the conventions a Japanese-language site needs from the 
start, and lets you complete a form **just by clicking field buttons** — a free,
one-time (buy-once), made-in-Japan plugin. No coding, and no per-feature add-on 
fees.

#### Running into these snags with the usual form plugins?

 * No built-in furigana field or postal-code-to-address auto-fill, so you fill the
   gap with add-ons or by hand
 * Just showing a confirmation screen before sending means adding another plugin
   or more configuration
 * You have to look up mail-merge syntax or HTML to get the notification and auto-
   reply you actually want
 * Every new field means learning a custom syntax, and the setup gets fiddly
 * Confirmation screens, advanced features, and add-ons sit behind monthly or yearly
   charges, and costs keep piling up

Putting up the form isn’t the finish line — it’s the start. Probono Form Basic takes
on exactly the day-to-day work that comes after.

#### With Probono Form, you just click buttons

Probono Form Basic builds your form **by clicking field buttons**. Name, furigana,
email, phone, postal code, address, inquiry details — click the ones you need, and
the form appears in the live preview on the right. No HTML, no memorizing shortcodes.

There are only three steps:

 1. Install the plugin and click “Activate”
 2. Click the field buttons to build your form
 3. Paste the generated shortcode into a page

That’s it — your Japanese contact form is live. The features that are expected but
tedious to set up — confirmation screen, auto-reply, spam protection — are **built
in and working from the start**.

#### How it differs from a typical form plugin

We won’t name names, but the differences from a typical form plugin are clear.

 * **Setup effort** — Typical plugins often expect you to learn mail-merge syntax,
   HTML, or a custom notation to get the form you want. Probono Form Basic is built
   to be assembled by clicking buttons, with no code.
 * **Fit for Japanese-language sites** — Whether the essentials a Japanese site 
   obviously needs are built in, with no add-ons: a furigana field, postal-code-
   to-address auto-fill, automatic honorific (san), a confirmation screen. Probono
   Form Basic was designed from scratch for Japanese-language sites.
 * **Cost** — Many plugins lock the confirmation screen, auto-reply, spam protection,
   or add-ons behind a higher monthly or yearly plan. Probono Form Basic is free,
   with a one-time (buy-once) philosophy. Costs don’t grow with every renewal.
 * **Data handling** — Probono Form Basic does not send what visitors submit to 
   external servers, and it does not track usage. Everything stays inside your site(
   except the postal-code lookup for address auto-fill — see “External services”).

#### Why “Japanese optimization” actually matters

On a Japanese-language site, how easy the form is to fill in directly affects how
many inquiries you get. Probono Form Basic solves that concretely.

 * **Postal-code-to-address auto-fill** — When a visitor types a postal code, the
   prefecture and city are filled in automatically. No more making people type out
   a long address by hand — and fewer drop-offs.
 * **Automatic furigana generation** — As the visitor types their name, the furigana(
   reading) field is filled in for them, removing the stress of entering readings
   manually.
 * **Automatic honorific** — In auto-reply emails and on the form, the honorific“
   san” is appended to the name automatically, keeping things polite by Japanese
   business norms.

“Fill it in without hesitation, in Japanese” — that obvious-but-overlooked baseline,
with no special configuration.

#### The tedious parts are automatic — so configuration stays minimal

Probono Form Basic includes many features, but **the number isn’t the selling point**.
What matters is that the processing a contact form actually needs works automatically
from the start. Misdelivery prevention via a confirmation screen, an auto-reply 
to the sender, spam suppression, double-submit prevention — the parts that are tedious
to build yourself are covered automatically just by adding the fields. So there 
are very few switches you actually need to touch. Read the list below as “what’s
already working behind the scenes.”

**Form basics**
 Unlimited form creation, duplication, deletion (single/bulk), form
renaming, 12 field types (name, furigana, email, phone, postal code, address, inquiry
type, inquiry details, checkbox, radio button, file upload, terms agreement), required-
field settings, real-time preview, shortcode output

**Confirmation screen**
 Show/hide the confirmation screen, customizable title and
message, editable button labels, success/error messages

**Email**
 Admin notification email, subject customization, CC/BCC settings, auto-
reply to the sender, reply-template selection

**Style**
 Form border on/off, 5 color themes, button shape, button fill, font size

**Japanese features**
 Postal-code-to-address auto-fill (zipcloud API), automatic
furigana generation, automatic honorific (san)

**Spam & misdelivery protection**
 Honeypot (bot trap), submission-time check, double-
submit prevention, misdelivery prevention via the confirmation screen

**Other**
 Responsive design, loading spinner on submit

#### What changes after you install it

 * Clicking field buttons gives you a complete form, confirmation screen included
 * Visitors just type a postal code to fill in their address, reducing mid-form 
   drop-off
 * The moment an inquiry arrives, the sender receives a polite auto-reply
 * Honeypot and submission-time checks suppress bot spam
 * One plugin lets you create unlimited forms for different purposes (contact, document
   request, recruiting, and more)

The time you spent agonizing over “how do I build this form” goes back to “how do
I respond to inquiries.”

#### Free and one-time — all of it

Everything above is **free**. No monthly subscription, no yearly renewal fee. “Try
it free first, confirm it fits my site, then decide” — being able to make that call
is the real value of a buy-once philosophy. Use it as your site’s inquiry desk without
worrying about creeping costs.

#### Why you can use it with peace of mind

 * **It doesn’t collect submissions** — What visitors enter is not sent to external
   servers or tracked as usage. Submissions stay within your site and your email(
   except the postal-code lookup for address auto-fill).
 * **No conflicts with other plugins** — Probono Form Basic works independently 
   and does not clash with other form plugins, avoiding trouble when switching or
   running side by side.
 * **Continuous development by Japanese developers** — Built and maintained by developers
   who understand Japanese-language sites, keeping pace with WordPress core updates.

#### When you want to go further (Pro)

When you need AI-powered text polishing or more advanced Japanese features, a separate
Pro version is available. See [https://form.prbn.org](https://form.prbn.org). Even
the Basic version is more than enough to set up an inquiry desk for your Japanese-
language site.

#### Just install it and try

A form isn’t something you “perfect before you publish” — it’s about quickly getting
to a state where you can receive inquiries. Probono Form Basic gives you that desk
with nothing more than **clicking buttons**. Free, buy-once, and no submission collection.
There’s nothing to lose.

Install it, press “Activate,” and click the field buttons. From that day, your Japanese-
language site has a contact form that simply works.

### External services

This plugin connects to the zipcloud API to retrieve address information from Japanese
postal codes. It is used to automatically fill in the address field when a user 
enters a postal code in the form.

The postal code entered by the user is sent to the zipcloud API only when the postal
code field is used and the user inputs a value.

This service is provided by IBS Co., Ltd.:

 * Form settings (form builder). Just click field buttons — name, furigana, email,
   postal code, and more — and the form assembles itself in the live preview on 
   the right. No coding knowledge required.
 * [[
 * Form management. Create unlimited forms for different purposes — contact, document
   request, recruiting. Copy each form’s shortcode and paste it to publish.

 * Confirmation screen (visitor view). Visitors review their input before sending,
   preventing misdelivery and giving a polite impression. Show/hide and wording 
   are fully configurable.
 * [[
 * Auto-reply settings. Send a polite thank-you email to the sender automatically—
   just pick a template. The input is inserted into the body, with a live preview
   on the right.
 * [[
 * Style settings. Adjust color (5 themes), button shape, font size, and more by
   clicking — no code — to match your site’s look.
