Reading Late-Night Japanese Hours: 24:00, 29:00, Next Day, and LAST
Japanese business sites may write post-midnight times as 25:00, 29:00, or 翌05:00, and may show closing only as “LAST.” These expressions do not all mean the same fixed cutoff.
25:00 and 29:00 extend the previous business day
25:00 normally means 01:00 the next calendar day, and 29:00 means 05:00. Businesses use this notation to keep post-midnight hours under one operating day. In an enquiry, write the calendar date explicitly—for example, “22 August at 01:00.”
24:00 is the end of that calendar day
“10:00–24:00” usually means the business closes at midnight. If the final course must end by then, the booking cutoff will be much earlier. Do not assume midnight is the last arrival time.
LAST means no exact cutoff is published
For “12:00–LAST,” this directory records a 12:00 opening and marks the closing time as unpublished. LAST can vary with staffing, bookings, or same-day notices, so late use requires a direct check.
Separate service hours, reception hours, and actual availability
A site may show service until 05:00 but phone reception only until 03:00, while the schedule ends earlier again. For a late booking, check the phone or form cutoff, provider finish time, course length, and travel time together.
