Kou Sennen is my best friend.

Sennenji is my best friend.

A special event was held to celebrate his 100th birthday anniversary.

I plan to travel to Spain next year.

He started a business without a plan, forgetting the lesson of 'peach and chestnut seeds take three years to bear fruit, persimmons eight years.'

In 1918, the Spanish flu spread all over the world, and many people died.

He has a Spanish friend.

He can speak Spanish fluently.

Due to the rain continuing for days on end, our picnic was cancelled.

He succeeded in a difficult project with the spirit of 'ishi no ue ni mo sannen', which means great works are performed by perseverance.
