OpenStreetMap
You’ve probably already seen the video of the Fukuoka sinkhole swallowing up large parts of an intersection. This obviously necessitates a map update, as it could be a little bit of an inconvenience to drive on this stretch.
In Japan updates are quick, both on the map and in the real world. From the detailed traffic restoration plan the road might actually be back to normal before any other map gets updated ;)

How splendid! I did not realise that the Japanese deployed British-style under-statement.
That is a smashing sinkhole, and well done for your rapid response in mapping it. However, at 30m it is a long way below the 120m Russian Sinkhole that emerged in September 2015.

Interesting you choose to change the map. Each situation is different and I bow to your local knowledge and how OSM japan do things but a similar case in the UK.
A railway line next to the sea was washed away in storms.

and took nearly 2 months to rebuild and reopen.
The decision was taken in the UK to not change the map at all and (I think) reverted any changes that were made.
The logic being that different providers take data and didn’t want to make this data out of synchronization with those providers that might update infrequently and this line will be opened again soon. Temporary closures like this are difficult to map and no real right or wrong answers.
