Okuricart

Okuricart extends WooCommerce for Japanese online stores (especially gift and food shops) with Japan-specific checkout features. The free version provides a reliable, well-designed “Japanese-style checkout”.

• Furigana (kana reading) fields, placed right after the name, auto-generated from the kanji as the customer types and fully editable
• Postal code to address autofill (uses the postal code data stored on your site, with an optional external API fallback)
• One-click import of Japan Post’s nationwide postal code data from the settings screen, with an optional monthly automatic update
• Remember input for next time (stored on this device only, no account required, opt-in, off by default)
• Free-shipping bar (“あと¥○で送料無料” / “¥X more for free shipping”) on the cart and checkout, using the free shipping threshold already set in your WooCommerce shipping zones
• Noshi (gift label) request at checkout: a “のしを希望する” checkbox and a free-text field for the label wording, shown on the order screen, emails and order details
• Delivery date and time slot request at checkout: the customer picks from dates built from your settings (lead time, selectable window, closed weekdays and specific closed dates), so holidays never appear as options
• Block checkout (Cart & Checkout Blocks) and classic (shortcode) checkout support, HPOS compatible

The premium version (sold separately) will add a shipping rate engine (carrier rates and estimated delivery dates), full noshi support (wording/mizuhiki rules, vertical preview, per-line labels), multiple shipping destinations, invoice documents, and repeat ordering.

External services

This plugin can connect to the zipcloud postal code API (https://zipcloud.ibsnet.co.jp/) to look up an address when the entered postal code is not found in the postal code data stored on your site.

• What is sent: only the 7-digit postal code the customer entered at checkout (no name, address, or other personal data).
• When: only when the postal code is not found in the site’s own postal code data. This can be turned off under WooCommerce > Settings > Okuricart (“外部APIでの補完”).
• zipcloud terms of use: https://zipcloud.ibsnet.co.jp/rule/api

This plugin can download the nationwide postal code data file from Japan Post (https://www.post.japanpost.jp/) to fill the on-site postal code database.

• What is sent: a plain HTTP GET request for the public data file (utf_ken_all.zip). No personal data or site information is sent.
• When: only when you click “全国データを取り込む” under WooCommerce > Settings > Okuricart, and (if “月次自動更新” is on) once a month in the background. Japan Post’s site terms: https://www.post.japanpost.jp/zipcode/dl/readme.html
