Languages
The calendar automatically follows the visitor browser language (Japanese or English), without a visible language switcher.
To explicitly choose the shortcode language, use [yoyakuflow language=”en”] / [yoyakuflow language=”ja”].
Admin screens follow the WordPress user locale. A readable Japanese JSON fallback is included for browser-language selection. org.
Facility names, descriptions, profile fields and booking fields use the labels entered by the administrator. There are no separate English content fields. Japanese and English customer email templates use the content entered by the administrator.
Only plugin content is switched; theme navigation, page titles and native date-picker language follow their own settings.
Week view
The All tab automatically allocates a published facility / staff member that is free for the entire selected range, using administrator resource order. Availability is rechecked under a database lock on submission. The confirmation and emails name the assigned resource.
Selecting an individual tab restricts the booking to that resource. Closed days, shifts, overnight hours and buffers still apply. Each date column has a configurable 70–240px minimum width and the schedule scrolls horizontally on narrower screens.
The optional monthly date picker can be hidden in Display settings.

Staff shifts
