A 27-year-old Japanese man has trended on social media because his unconventional name of “Happy” has brought him just the opposite.

After Terauchi Happy’s story was reported by ABEMA Prime TV at the end of March, a heated discussion about unusual names was triggered on the internet.

His name was given to him by his mother to mark the overwhelming joy she felt when Terauchi, her first child, was born.

But she did not expect his name would bring him so much trouble.

Terauchi’s name attracted much attention at school and led to him being bullied.

He hates birthdays or holidays because people would greet him using the word happy, such as Happy Birthday and Happy Valentine’s Day, which would lead to ridicule.
