Bay Influence page. The original text stated the 2018 yamase event lasted “19 days.” JMA reanalysis of the easterly flow period supports 17 days. Original: 19 days. Corrected: 17 days. Flagged by a reader in Chiba; thank you.
Seasonal Matrix page. The November text previously said Boso's November mean exceeds Saitama's by “2°C.” The 1991–2020 normals support 1.5°C. Original: 2°C. Corrected: 1.5°C. Found in internal review against the normal-period tables.
Tama Hills page. Urban forest cover in the 23 wards was stated as “9%.” The Tokyo Metropolitan Government survey figure is 8%. Original: 9%. Corrected: 8%. Flagged by contributor review.
Saitama Plains page. Frost-day count for the plains was originally published as “25–30/year.” Recomputed against the 1991–2020 normals from the Saitama observatory and cooperative records: 28–35/year. Original: 25–30. Corrected: 28–35.
Zone map. The Yokohama marker label was initially placed inside the Tama River's label arc, causing overlap at small viewports. Cartographic error, not data error; repositioned. No figures affected.
How to report an error
Email [email protected] with the page name and the figure in question. Cite your source — a JMA table, an official report, an instrument record. Reader-flagged corrections are reviewed against primary sources before entry here, and the reader is credited unless they prefer otherwise. Corrections to purchased guides trigger the automatic-refund offer described in the refund policy.
We'd rather this page be long than short. A corrections log with entries is evidence of a working review process; an empty one is evidence only of an unexamined archive.
