Question:

We found this in the guideline: Some locales, especially in Japan, use a lot-based addressing system rather than the street-based address system that is used in the rest of the world. In such locales,named areas of cities should use the <city_district> mention, numbered districts, city blocks and building numbers should all use the <building_number> mention(e.g. the chome, banchi and go in Japan) and the <street> mention should not be used.

"世 田 谷 ど お り" is a specific road in Japan, so we tag it as <city_district> rather than <street> based on above. We are confused why it belongs to <street>. Kindly let us know your thought, thanks!
