Comment from pnorman
this seems to have made some problems around https://www.openstreetmap.org/relation/812190#map=18/34.25831/136.58273 where the admin geoms are separate from the coastline. It's also fairly absurd to represent the admin boundary as thousands of little islands

Thank you for your feedback. It needs clean up indeed.
Please let me clarify the policy to fix them.
I guess we have 3 approaches.
Which one is your thinking of?
If they all wrong, could you tell me the sample relation id as our ideal one?1-1. delete island_admin boundary ways.
1-2. redraw them as same as geom on coastline.
1-3. set new admin boundary way to relation as outer role member.2-1. delete island_admin boundary ways.
2-2. add boundary=administrative tag to coastline ways.
2-3. set them to relation as outer role member.3-1. delete island_admin boundary ways.
3-2. delete coastline_admin boundary ways.
3-3. enclose admin boundary ways using the way on sea.
Result should be like this.
http://www.openstreetmap.org/relation/4089279But I guess 3rd is not landarea boundary, it is similar to maritime baseline.

I'm now working on next (Aichi prefecture) import.
I'll care them after Aichi import action. -
Comment from nyampire
As I checked foreign (mainly Europian) method, the coastlines are included in administrative boundary relation.
My correction is here.

Is this method similar to your intention?
If yes, I'll apply it to the other municipalities as clean up.
