Japanized for WooCommerce

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 31% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Modeled within the band wp.org reports; tightens as we track daily.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A declining trend compresses what a buyer would pay.

   食料品には対応してない印象を受けます。生鮮食品関係のECで無料版を利用していますが、いくら休日期間を設定してもお客側からは配達希望日を設定できてしまいます。商品の消費期限が短く出荷調整などがあるため、こちらで休日とした日はお客側には配達希望日として表示しないようにして頂けると助かります。3年前のフォーラムでも似たような質問（配送に関する新機能希望2020年3月25日）が出ていて機能追加される旨が書いてありましたがプロ版では対応されていますか？

   昨日にインストールして色々と設定を行っています。 WooCommerceを日本の商習慣にローカライズするプラグインで使いやすいです。 ありがとうございます。 １点、不具合（なのかな？） 配達予約可能開始日で当日配送ができる場合は0を入力してください、とあったので0を入力すると、なぜか2で表示されます。 2を入力した時も２で表示されるので見た目からは違いが分かりませんでした。 バージョンは2.2.12 WPのバージョンは5.6.2 です。
