In July 2008, company employee Yasushi Takahashi decided to ask his girlfriend of eight years to marry him and was determined to make it "the world's biggest proposal." So he quit his job and went off on a six-month journey across Japan — on foot and by car, ferry and bicycle.

After 7,160-km of travel that took him through 40 prefectures, Takahashi's unique marriage proposal was finally ready: the Global Positioning System records of his journey spelled out the phrase "Marry Me" across the Japanese archipelago, covering Honshu, Kyushu and Shikoku. In Hokkaido, meanwhile, he traced the shape of a heart speared by an arrow.

Fortunately, she said yes. "It was a big surprise," she was quoted by Takahashi as saying. "I felt the greatest love in the world."
