What is the exact reason behind the usage of がin the following phrase?


Hopefully, just another quick one here.

In the phrase

> 日本で東京スカイツリーが一番高い建物です。

what is the reason behind using が as opposed to は in the phrase

> 東京スカイツリーは日本で一番高い建物です。

Sorry if this is a silly question... But thank you nonetheless!!




> 日本で東京スカイツリーが一番高い建物です。

It is Tokyo Skytree that is the tallest building in Japan.

This describes which one is the tallest. が is used to feature something
particular rather than the others.

> 東京スカイツリーは日本で一番高い建物です。

Tokyo Skytree is the tallest building in Japan.

This just describes Tokyo Skytree.
