You installed a foreign-made SEO plugin, but between the half-English settings screen and the endless switches, you never figured out what to actually configure — so it just sits there, half set up.
You run a Japanese-language site, yet the tool wasn’t built for Japanese text. Character-count guidance is tuned for English, there are countless options, and you can never quite tell whether any of it is actually working on your Japanese posts. Before long you’re spending more time configuring the SEO tool than doing SEO. ProbonoSEO Basic exists to end exactly that.
ProbonoSEO Basic is a free, made-in-Japan SEO plugin that starts working automatically the moment you activate it. No expertise, no long setup wizard. The essentials for a Japanese-language site are simply on.
<h4>Tired of this with foreign-made SEO plugins?</h4>
<ul>
<li>Too many options — you can’t tell which ones to touch</li>
<li>Character-count and separator optimization assume English, so it never matches how Japanese actually looks</li>
<li>Getting real value out of it requires tutorials, or a paid course</li>
<li>Yearly renewal fees and monthly subscriptions that keep piling up</li>
<li>It claims to do dozens of things, yet you can’t feel what is actually working</li>
</ul>
The more a tool competes on feature count, the deeper the configuration swamp gets. ProbonoSEO Basic chose the opposite path.
<h4>With ProbonoSEO, you just install and activate</h4>
ProbonoSEO Basic ships with the commonly used basics already switched on. Title optimization, automatic meta descriptions, canonical URLs, structured data (schema), breadcrumbs, internal links, and page-speed groundwork all start working the instant you activate it.
There are only two steps:
<ol>
<li>Install the plugin</li>
<li>Click “Activate”</li>
</ol>
That’s it — the SEO foundation for your Japanese-language site is in place. You can fine-tune every switch in the admin screen if you want, but it is designed so that doing nothing still works correctly from the start.
<h4>How it differs from a typical foreign-made SEO plugin</h4>
We won’t name names, but the differences from a typical foreign-made SEO plugin are clear.
<ul>
<li>Setup burden — Typical foreign-made plugins ask for a lot of upfront configuration and learning before they pay off. ProbonoSEO Basic assumes the basics are auto-on and that it should “work without being configured.”</li>
<li>Fit for Japanese — Whether the tool is built around Japanese text structure: character-count feel, separators, and natural summaries. ProbonoSEO Basic was designed from scratch for Japanese-language sites.</li>
<li>Cost — Many foreign-made plugins lock their better features behind a monthly or yearly subscription. ProbonoSEO Basic is free, with a one-time (buy-once) philosophy. Costs don’t grow with every renewal.</li>
<li>Data handling — ProbonoSEO Basic sends no data to external servers and collects no usage statistics. Everything stays inside your site.</li>
</ul>
<h4>Why “Japanese optimization” actually matters</h4>
In the end, SEO quality comes down to one thing: does it read naturally as Japanese? ProbonoSEO Basic solves that concretely.
<ul>
<li>Titles and meta descriptions — Automatically tuned to a length that won’t get truncated in search results (meta descriptions around 70–120 characters). It picks the best separator for Japanese and tidies up full-width/half-width characters and symbols.</li>
<li>Natural summaries from your content — It generates a natural Japanese description from the article body, smoothing conjunctions and sentence endings. Even when the excerpt field is empty, you still get a search-ready description.</li>
<li>Automatic duplicate avoidance — Detects duplicate titles and descriptions and warns you, reducing the risk of diluted ranking signals.</li>
</ul>
“Reads naturally in Japanese” — that obvious-but-overlooked baseline is guaranteed with zero configuration.
<h4>Built for the age of AI search</h4>
Search is rapidly shifting from a list of links to AI that generates the answer. Whether you get cited and referenced by AI search — ChatGPT, Perplexity, Google AI Overview — will increasingly decide your traffic.
ProbonoSEO Basic meets that shift head-on (AIO = AI Optimization).
<ul>
<li>Allow AI crawlers — Automatically appends major AI crawlers such as GPTBot, ClaudeBot, PerplexityBot, and Googlebot-Extended to robots.txt (it never rewrites existing rules — it only appends at the end). This makes your site available for AI to read.</li>
<li>Structured data output — Emits FAQ (FAQPage), Article, and Organization structured data so AI can accurately understand and quote your content.</li>
</ul>
Search-engine optimization and AI-search optimization, handled by a single plugin — both with nothing more than “activate.”
<h4>What changes after you install it</h4>
<ul>
<li>Just publishing a post automatically produces search-ready titles, descriptions, and structured data</li>
<li>Shares on social platforms (Facebook, X, LINE) keep their intended appearance</li>
<li>Breadcrumbs and internal links convey your site structure and improve navigation</li>
<li>Lazy-loading for images/iframes and script optimization lay the groundwork for faster pages</li>
<li>AI crawlers and structured data prepare your content to be picked up by AI search</li>
</ul>
The time you used to spend wondering “what do I need to configure for SEO?” goes back to writing.
<h4>Mostly automatic — so configuration stays minimal</h4>
ProbonoSEO Basic includes many features (74 items), but the number isn’t the selling point. What matters is that nearly all of them work correctly and automatically from the start. So there are very few switches you actually need to look at. Read the list below as “what’s already working behind the scenes.”

<h4>Why you can use it with peace of mind</h4>
<ul>
<li>No data collection — No data is sent to external servers and no usage is tracked. Everything stays within your site.</li>
<li>Automatic conflict avoidance — Even if another SEO plugin is already installed, ProbonoSEO Basic automatically detects it and suppresses duplicate output, avoiding trouble when switching or running side by side.</li>
<li>Continuous development by Japanese developers — Built and maintained by developers who understand Japanese-language sites, keeping pace with WordPress core updates.</li>
</ul>
<h4>When you want to go further (Pro)</h4>
When you need AI-powered SEO assistance, competitor analysis, or more advanced rich snippets, a separate Pro version is available. See <a href="https://seo.prbn.org" rel="nofollow ugc">https://seo.prbn.org</a>. Even the Basic version is more than enough to put a solid SEO foundation under your Japanese-language site.
<h4>Just install it and try</h4>
SEO isn’t something you “perfect before you start” — it’s about getting the right foundation in place quickly and then keeping writing. ProbonoSEO Basic gives you that foundation with nothing more than activating it. Free, buy-once, and no data collection. There’s nothing to lose.
Install it and press “Activate.” From that day, your Japanese-language site starts moving toward being picked up by search — and by AI search.

uniple

uniple checkout for WooCommerce lets merchants accept JPYC, a Japanese yen stablecoin / electronic payment instrument (電子決済手段), through uniple’s hosted checkout.
Shoppers choose the uniple payment method in WooCommerce and are redirected to the uniple checkout page. uniple handles wallet connection and settlement, then returns the shopper to the WooCommerce order-received page. Payment confirmation is applied through a signed webhook, with a server-side session lookup fallback when the return page is reached before the webhook arrives.
Features:
<ul>
<li>Redirect-only WooCommerce payment gateway.</li>
<li>Classic checkout and Cart / Checkout Blocks support.</li>
<li>High-Performance Order Storage (HPOS) compatibility.</li>
<li>HMAC-SHA256 signed webhook verification.</li>
<li>Atomic webhook idempotency lock and event history.</li>
<li>Return URL order key verification and live lookup fallback.</li>
<li>Masked API key and webhook secret fields in the WooCommerce admin.</li>
</ul>
This plugin is built for WooCommerce stores. It is not developed by, affiliated with, or endorsed by WooCommerce or Automattic.
<h3>How to obtain an API key</h3>
uniple checkout requires a merchant account with uniple. Apply for an account at:
https://forms.gle/b8kwVZeynA1ffV8j6
After your application is approved, uniple will issue your API key and webhook secret, which you enter in the plugin settings (WooCommerce → Settings → Payments → uniple checkout (JPYC)).
<h3>External services</h3>
This plugin connects to the uniple hosted checkout API. The default service endpoint is <code>https://uniple.io</code>; the settings screen also permits <code>https://dev.uniple.io</code> for test use.
The plugin sends data to uniple only when it needs to create or verify a checkout session:
<ul>
<li>When a shopper places an order with the uniple payment method, the plugin sends <code>POST /api/merchant/checkout/sessions</code> to the configured uniple API base URL.</li>
<li>The session creation request includes the order total as <code>amountJpyc</code>, the WooCommerce order ID as <code>clientReferenceId</code>, the order description / order number, the configured merchant label, a one-line item summary, the success URL, the cancel URL, and the webhook URL.</li>
<li>The session creation request also includes the merchant API key in the <code>Authorization</code> header and a plugin <code>User-Agent</code> containing the plugin version, WordPress version, and WooCommerce version.</li>
<li>When the shopper returns from hosted checkout before the webhook has completed the order, the plugin may send <code>GET /api/merchant/checkout/sessions/{sessionId}</code> to verify the session status. This request includes the uniple session ID, the merchant API key, and the same plugin <code>User-Agent</code>.</li>
<li>uniple sends payment webhooks back to the store at <code>/wp-json/uniple/v1/webhook</code>. The plugin verifies the webhook signature locally with the configured webhook secret.</li>
</ul>
The plugin does not send full billing addresses, shipping addresses, customer account details, card details, wallet private keys, or browser cookies to uniple.
