Popular singer Tomomi Kahara (39) recently revealed at a blood drive awareness event at Budokan in Tokyo that her blood type is in fact type O, not A.

Kahara discovered this when she had blood donated in Shibuya when she was 36. When Kahara was born, there may have been a mixup with her mother’s blood, as she was identified at the time as type A.

Kahara said “I had been living 36 years as a type A, and I wondered ‘What’s going to happen to me?’ as I became really depressed on the Yamanote train going home.”

“I was able to find my true blood type through donating, so I hope everyone donates too.”
