One of the two or three people I follow on Twitter is the American author Craig Mod.
Craig is based in Japan, and over the past 5 years he has developed an interesting set of email newsletters, and a distinctive approach to long-distance walks across Japan.
His most recent long walk has just finished (HERE): it was nearly 700 kilometers over five weeks. Most of that distance was along the Tokaido, the historic highway that connects Tokyo and Kyoto. During the walk he sent a daily email and photo (which were great), and invited readers to respond to his walk. HERE is his immediate post-walk summary, but he will no doubt write and publish a book on his experiences.
