It is a 1936 506 model, which is also my favourite, together with the 507 which is pretty much the same except for the second chest pocket.
Probably the best budget denim jacket there is. They are currently having a campaign with a reduced price, it is now 14 700 yen instead of 19 800. Very limited numbers though, there are like 5 jackets left.
The denim is around 14-15oz and is slightly slubby. The texture is much like that of my Samurai's, but the color is different.
