NHK World 'On Demand' service has some interesting programmes. At the moment, you can watch an episode of 'Design Talks Plus' called 'Design Hunting in Aomori'. I don't know how long it will be available, so if you want to watch it, click the link now.
It features koginzashi, showing some of the collection of mother and daughter Akiko and Maiko Ishita. It also shows how kogin is stitched and visits the Kogin Institute in Hirosaki.
Other items in the programme include a look at the work of printmaker and painter Shiko Munakata, including archive footage of him cutting printing blocks.
His work drew on the imagery of the Nebuta festival in Aomori (Neputa in Hirosaki).
Bunako is another local craft shown in the programme, creating three dimensional forms from ribbon-like strips of beechwood.
If you're interested in Japan, you will find a lot of excellent viewing on NHK World.
