✎ Updated 20 Aug 2026 Publication date recorded for 2 sources. What changed →
Yokohama's city planning bureau publishes an annual visitor count for the Minato Mirai 21 waterfront district, and in 2025 it changed how the number is made. The old method estimated a year from people crossing into the district between fixed hours; the new one estimates time spent inside it from smartphone location data supplied by Agoop, and adds the Yokohama Station East area to a measurement zone that previously covered only the Chuo and Shinko districts. The city published about 101.8 million visitors for 2025 — and, in the same release, that this is about 8.3 million fewer than the year before on the same method.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went. All four grades →📊 Impact
About 101.8 million visitors in 2025 on the new method, some 8.3 million fewer than 2024 measured the same way, against about 82.6 million reported for 2024 under the old entrance-crossing method. Workers in the district reached a record of about 147,000.
🎓 Lesson
Put the two published headlines side by side and the district grew by roughly a quarter; read the city's own footnote and it shrank by 8.3 million people. The break is disclosed, in a sentence most coverage drops.
