Observed 2026-08-08 – 2026-09-06 Cities 25 Hotels 4,372 Observations 3,827,714

Japanese hotels cost 2.4× more on a Saturday. In Bali, the day of the week does not exist

We re-ask the price of 4,372 hotels across 25 Asian cities every day and keep every answer. 3,827,714 of them so far. This is the first thing that jumped out.

1. The ratio, city by city

Third Tuesday against third Saturday of the same month

Same city, same month, same room count. We hold everything else still: two adults, one night, hotels only (no whole-apartment rentals), and the median rather than the mean so a handful of suites cannot drag the number around.

Figures are Korean won, the currency we record everything in. The ratio is what matters here, and a ratio is the same in any currency.

Japan and Taiwan run 1.30× to 2.36×. Southeast Asia runs 0.99× to 1.09×. In Nha Trang, Cebu, Koh Samui, Bali, Da Nang, Phu Quoc the day of the week barely registers at all.

In Fukuoka, shifting your stay by one night changes the bill by roughly 1.4×. In Bali, it changes nothing.

2. The whole week

Indexed so both ends fit on one axis

Plotting the raw numbers does not work: Fukuoka on a Saturday and Bali on a Saturday are an order of magnitude apart, and the lower line flattens against the floor. Setting Tuesday to 100 keeps only the thing we care about — how much a city moves.

Tuesday = 100. Hover any point for its value. This chart is not the same data as the table above. The table comes from dates pinned to a specific Tuesday and Saturday; this comes from a rolling window where all seven weekdays appear. Two different slices, nearly the same ratios.

Saturday is not where it starts. Friday in Fukuoka already runs 43% above Monday.

Bali goes the other way entirely: all seven days land between 17,442 and 17,582 won — a spread of 0.8%. There is no weekend there, price-wise.

3. Not a one-month fluke

Same ratio, six months running

A single festival weekend could produce a number like this. So we split it by month.

It holds every month.

4. Public holidays barely move it

The weekend is a stronger force than the calendar

Across the six Japanese cities, an ordinary weekday sits at 97,519 won. Measured against that:

5. How this was measured

  1. 2026-08-08 to 2026-09-06 (30 days), asked at the same time each day.
  2. Held constant: 2 adults, 1 night, hotels only, median not mean.
  3. Rates are as observed — before coupons, excluding taxes and service charges. Checkout will be higher.
  4. What this cannot tell you: how far in advance to book. That needs a single date tracked from months out all the way to arrival; 30 days is not enough yet.
  5. What this cannot tell you: which city is cheapest overall. Our sample skews to different hotel grades in different cities, so raw city-to-city price comparison is not sound. Ratios within a city are.
