Kunihiko is my best friend.

Yoshikuni is my best friend.

He traveled around various countries and learned about their cultures.

He was born as an illegitimate child and experienced many difficulties.

My grandfather used to till his privately-owned rice field.

Using the private railway makes commuting very convenient.

We respect Japanese culture.

We are going on a trip tomorrow.

He holds a personal grudge against me.

My personal thought is that everyone should be treated equally.
