Medieval reenactment in Japan?

I really love the ancient and medieval history of my country (Italy) and Europe.
In fact I'm a member of an italian Reenactment group from XII-XIII century.

I read that there are many festivals about medieval age in Japan (Jidai Matsuri). However, I do not find anything about Reenactment groups from Japan. Somebody know more about it? Thanks.

...as you said, there are so many historical festivals around Japan. It seems that most of Japanese reenactors are into Sengoku period and that lots of those in armor are active in participating in such festivals as an individual or a group.

FYR, samples of samurai reenactment groups:

Thank you for the precious informations.
I never found some website about japanese reenactors. I think that the first group is about kamakura period (1185-1333).
I can not see the second link.
The last link about "medieval europe" is strange. I think it is a group about "medieval fantasy". In fact there are armors and costumes used only for fun, with no (or little) historical accuracy.

You should be very happy that Avalon participants are at least interested in European medieval history!

Why should you expect them to be accurate? this is not part of their culture at all. How accurate are any representations of ancient Japanese life in Italy, if any???

Even in Europe not every historical pageant is accurate, far from it!
In my native region of continental Europe there is a yearly medieval pageant about the hundred years war.
Both the public and the participants aren't all aware that during the Middle Ages the English kings and most English aristocrats spoke French... not English....(this is why the coat of arms of the UK crown has mottoes in French: "Dieu et mon droit" and "Honni soit qui mal y pense" )
see http://en.wikipedia.org/wiki/File:Royal_Coat_of_Arms_of_the_United_Kin...

All hobbies (including sports) have people that are obsessed by accuracy in thousands of minute details of things, times and places and people that only want a pleasant fantasy for a while.
Both have their place and neither side should put down the other.

There are a lot of groups like Avalon in Europe and USA too. It is not bad, of course.

Reenactors are commonly divided into three categories, based on the level of concern for authenticity. You can read here, for more informations:
