Guide

How to Use HanSanDay

HanSanDay shows how crowded Japan's theme parks are with a 0–100 score and 6 levels, so you can tell at a glance when it'll be quieter to visit.

01

Crowd score 0–100

The more people, the higher the score. From 0 (very quiet) to 100 (very crowded), the colors run like a traffic light — green (quiet) to red (crowded). It's calculated from real wait-time data.

02

90-day calendar

See the next 90 days from today all at once. Use each cell's score and color to quickly spot the quiet days, and tap a date to see the detailed forecast for that day.

03

Overlay Korean, Japanese & Chinese holidays

Toggle the public holidays of Korea, Japan, and China on or off. That way you can plan around the long weekends when tourists tend to pile in.

04

Pass & DPA analysis

Whether a USJ Express Pass or a Tokyo Disney DPA (paid priority entry) is worth it that day — we work out the wait time you'd save, the value for money, and the best route to take. You can switch the date and park instantly with the buttons.

05

One-line AI analysis

For key dates, AI reads the crowd context for that day and sums it up in a single line, from a Korean, Japanese, and Chinese perspective each.

06

Data sources

Real-time wait times come from Queue-Times, weather from Open-Meteo, and public holidays from the Public Data Portal, holidays-jp, and holiday-cn. This is an unofficial service.

Frequently Asked Questions

What is HanSanDay?+

HanSanDay is an unofficial crowd-calendar that translates real-time wait times at Japan's theme parks (USJ, Tokyo Disneyland, Tokyo DisneySea) into a single 0–100 crowd score, so you can see up to 90 days ahead which dates will be less busy.

How is the 0–100 crowd score calculated?+

We start from real-time attraction wait times via Queue-Times, then factor in public holidays in Korea, Japan and China plus the weather (Open-Meteo) to convert it into a 0 (very quiet) to 100 (very crowded) score. A higher score means more people — it's a 'crowd temperature,' not the air temperature.

Is this an official service?+

No. HanSanDay is an unofficial service with no affiliation to USJ or Tokyo Disney Resort. All names and trademarks belong to their respective owners — please check the official sites for actual operating and pricing information.

Which parks are supported?+

We currently cover three parks — Universal Studios Japan (USJ, Osaka), Tokyo Disneyland and Tokyo DisneySea (Chiba) — with a 90-day crowd calendar and a 'is the pass worth it?' value analysis for each.

How often is the data updated?+

Real-time wait times come from Queue-Times, holidays from the public data portal, holidays-jp and holiday-cn, and weather from Open-Meteo, all refreshed regularly. The service is available in Korean, Japanese and Chinese.
