Tenjin Matsuri in Osaka, Japan

Letter Writing Day in Japan on July 23 (The Letter Writing Day can be a bit confusing... as we found on numerous sites that this 'holiday' falls on 7th of December, then again on the official World Letter Writing Day page the date is 1st of September, and Japan issues LWD stamps each year, for over two decades now, on 23rd of July. In any case, its a nice way of reminding people of the existence of letters);
