"Across the Sea" is the fifth song from Weezer's second album, Pinkerton. Singer/songwriter Rivers Cuomo wrote "Across the Sea" after receiving a letter from a Japanese girl during a depressing winter at Harvard University. Cuomo remarked, "When I got the letter, I fell in love with her. It was such a great letter. I was very lonely at the time, but at the same time I was very depressed that I would never meet her. Even if I did see her, she was probably some fourteen-year-old girl, who didn't speak English." When asked in 2006 about the girl, he commented that "I don't know anything about her and I've never contacted her." The lyrics also make mention of Cuomo's adolescent consideration of becoming a monk to win the favor of older women, as well as the idea that his mother is responsible for his romantic shortcomings.
