Hello Ikuta.
Thank you for editing!

I found you might import the Plateau dataset in the following changesets.
Importing those should be operated with import guidelines.
(the import discussion is not finished, and it needs a dedicated account, and so on)

I want to revert those.
Sorry for inconvenience!
