Maybe it is then. Friends of mine who lived there longer-term said the usual response was something to the extent of a confused stare and "Um, well, it's good that you've found a hobby...". Is this really the analogous situation, though? I don't think anyone here mentioned looking to become a samurai or ninja. Just that they did koryu budo, or that they did x-ryu y-jutsu. Why would this be the case, though? Are ninja movies or other forms of media-ninjitsu still big business out there? (The American ninja-boom has thankfully faded, but sometimes I'm not convinced it's gone.) Here's a question that got me thinking; what constitutes membership of a koryu when the ryu's gotten all worldwide-scaled to the point of fragmentation (e.g. Muso Shinden Ryu)?
