Yuki & Lucas: When Kyoto Met São Paulo

She spoke only Japanese. He spoke only Portuguese. They found each other on Heartline — and then found a language neither of them had expected.

Yuki & Lucas: When Kyoto Met São Paulo

Yuki was 27, a graphic designer in Kyoto. She had never been to South America. She had no reason to think about Brazil.

Lucas was 29, a musician in São Paulo. He knew three Japanese words: sushi, anime, and arigato. He typed them into Google Translate regularly, for reasons he couldn’t quite explain even to himself.

They matched on Heartline on a Tuesday in October.


“I almost didn’t message him,” Yuki says. “His profile photo showed him laughing. I liked the laugh. But I thought — we don’t share a single word. How would this work?”

She sent a message anyway. In Japanese.

On Lucas’s screen, it appeared in Portuguese: “Your laugh looks like it comes from somewhere real.”

He stared at his phone for a long time.


Their first voice call lasted four hours.

“It was strange at first,” Lucas remembers. “I’d say something, and then there’d be this tiny pause, and then her voice would come back — but in Japanese, obviously, so I couldn’t understand that either, and then the translation would play for me in Portuguese.” He laughs. “But somehow you stop noticing. You start watching how she says things, not just what the words mean.”

Yuki describes it differently: “I felt like I was talking to someone who understood me before I finished speaking.”


Six months later, Lucas flew to Kyoto.

He had learned approximately forty words of Japanese by then. Yuki had learned fewer than that in Portuguese. They spent ten days walking through temples and izakayas, their phones pressed to their ears when sentences got complicated, mostly not needing them.

“Language is a tool,” Lucas says. “But it’s not the thing. The thing is something else. I don’t know the word for it in any language.”

Yuki laughs when she reads that. “I think the word is us.”


They’re long-distance still — Tokyo to São Paulo is not a short flight. But they call every day. Voice, mostly. Sometimes video when the lighting in Yuki’s apartment is soft and Lucas has his guitar.

“I’m learning Portuguese properly now,” Yuki says. “But I think I fell in love before I knew a single word of it. Is that strange?”

No stranger than anything else that Heartline makes possible.
