About IKOKA

The question we heard most from friends visiting Japan was not “what should I see?” — guidebooks answer that well. It was “is it crowded right now?” Fushimi Inari at 7 a.m. and Fushimi Inari at 2 p.m. are two completely different experiences, and a festival that looks magical on a poster can mean an hour in a queue just to leave the station.

IKOKA puts the answers to those practical, in-the-moment questions on one page: how busy a famous spot is likely to be this hour, how long the waits are at the big theme parks, what something costs in your own currency, which festivals are coming up and where to watch them without the crush. Everything is designed for a phone held in one hand, in five languages: Korean, English, Japanese, Simplified Chinese and Spanish.

We also had people who live in Japan in mind. Residents plan weekends around the same holidays and festivals as visitors, and a calm-route suggestion is just as useful to someone from Osaka as to someone from Seoul or Madrid.

Crowd levels are estimates, not live headcounts. We combine the typical hourly and weekly rhythm of each place, Japanese public holidays and peak seasons (New Year, Golden Week, Obon and others), and the festivals and events listed on this site. The result is a reasonable guess about how busy a place is likely to be — we always label it as an estimate and never present it as a measurement. We show the result on a simple five-step scale: LEVEL 1–2 (very calm, calm) in green, LEVEL 3 (moderate) in yellow and LEVEL 4–5 (busy, very busy) in red, with the underlying 0–100% estimate in small print.

Theme park wait times come from the free themeparks.wiki API, which collects the waits that the parks publish. Exchange rates come from the Frankfurter API (based on central-bank reference rates) with open.er-api.com as a backup. Both are shown with the time they were fetched, and both can lag behind what you will actually pay at a counter or ATM.

Live cameras are public YouTube streams run by their owners. Japanese public holidays come from the open-source holiday_jp dataset. Photos come only from Wikimedia Commons under free licenses, and every photographer is credited on our photo-credits page.

Festival dates are checked by hand against the organizer’s own website — the shrine, the city or the organizing committee — and that page is linked from every festival entry. When the organizer has not announced next year’s date yet, we show the usual timing and mark it “date TBC” instead of guessing.

Our blog articles are drafted with the help of AI tools. A draft is never published as-is: every factual claim must point to an official or primary source — a government page, a transport operator, a tourism board, an event organizer — and it is checked against that source before publication. A human editor reads and approves every article, in every language, before it goes live, and the sources are listed at the end of each post.

We try to write the way a well-informed local friend would talk to you: specific, practical and honest about the downsides. If something is expensive, crowded or not worth the detour, we would rather say so.

Prices, timetables and rules in Japan change. If you find something out of date or wrong, please tell us through the contact page — corrections are always welcome and we fix confirmed errors quickly.
