Sega will send off Hatsune Miku Project Diva F with a pre-launch festival in Yokohama. The Summer's End 39 Festival event will be held on August 29 from 12:00 to 21:00 (the "39" in the name is a play on the word "Miku"). Attendees can look forward to live performances, carnival games, demos, and goods sales. Admission is free.

While the event is open to everyone, Sega will open a special "water stage area" to just 2,000 people. You can put your name down for access at the Miku official site.

In other Miku promotional news, Sony will be releasing a special Hatsune Miku walkman to commemorate the franchise's fifth anniversary. The walkman will be available in blue and black color variations, and in blue with speakers attached. Only 3,939 units of each variation will be produced.
