On 30 June 2008, Yasushi Takahashi, or Yassan for short, quit his job to begin his journey across Japan armed with his GPS logger to document the experience.
However, this trip is not only for Yassan to discover the "Japan that [he knows] only in books", but it would decide his future.
Yassan filmed parts of his adventure in his YouTube video titled Tegami ~ Letter.
According to RocketNews24, he set out on his 31st birthday from Hokkaido, following a carefully designed route which sometimes led him to roads less travelled.
A few days before New Year, he was already on the last leg of his journey.
Finally, he made it to his destination, marking the end of his half-a-year trek and the message drawn for his girlfriend.
Yassan was greeted with great news as his girlfriend accepted the proposal.
A few years later, he received another piece of good news from the Guinness Word Record. His letter was recognised as "The World's Largest GPS Drawing" at 7,164 km long.
This is his video documenting the journey.
