The powerful earthquake, followed by hundreds of aftershocks, injured at least 330 people, according to local authorities.
The quake left thousands of households across Ishikawa without electricity or water as rescuers struggled to reach isolated communities cut off from help.
“I also wish speedy recovery to the injured. Our thoughts are with you and the people of Japan during this difficult time,” said Mr Lee as he concluded his letter.
