Kunimitsu is my best friend.

He was deeply involved in the politics of the republic.

His new game is very popular in the netizen community.

The culture of Russia (obsolete term) is very interesting.

His country was under the influence of the suzerain for a long time.

This ancient artifact is very valuable.

It is very interesting to learn about ancient history.

That thing is important to me.

I love Japan.

Ancient Japan was a place where beautiful nature and culture merged.
