Finnish academic male choir KYL has been touring Japan. The tour included 5 concerts, from which 4 were fully booked. The tour also included lots of other finno-japanese cultural exchange.
The special kicker in this case was that at the same time, the Choir was spreading Bitcoin propaganda to Japan, as LocalBitcoins was sponsoring the concert. LocalBitcoins was prominently displayed in the tour t-shirts, as well in the concert promotional material.
At the same time, Japanese translation was made to LocalBitcoins, making it more usable for Japanese audience.
