Hello,
We are seeing what appears to be a regression in Looker Studio Geo Chart / Filled Map for Japan.
Issue summary:
-
Prefecture level (1st level administrative division) still works correctly.
-
Municipality level (city / ward / town / village, using 2nd level administrative division) is no longer working properly.
-
This had been working until around April 30, but appears broken since early May.
What we observed:
-
Existing reports that previously displayed municipality-level filled maps correctly are now broken.
-
Newly created charts show the same issue.
-
Reports created by different users are also affected.
-
Table charts using the same data source display the raw values correctly.
-
Heatmaps / other map visualizations still appear to work.
-
Only Geo Chart / Filled Map at municipality level seems affected.
Examples (Japan / Hokkaido):
-
Prefecture level: Hokkaido displays correctly.
-
Municipality level values such as Sapporo, Eniwa, etc. do not render correctly on filled maps.
Data source:
- Google Sheets (also reproduced across multiple reports)
Question:
Is there a known issue or recent change affecting Japan municipality-level geo mapping in Geo Chart / Filled Map?
Any workaround or ETA for fix would be appreciated.
Thank you.
