I started to write a bit about my own initial involvement in Japanese culture, but this got long and wordy. Suffice it to say that my initial experience with Japanese culture was more along the lines of Tokion, Mangajin, the Spoozys, the Plastics, & Pizzacato Five, rather than anime etcetera... I was lucky enough in 2000 to move next to the girl who would be my first Japanese crush... she taught me a lot about Japanese culture, and the language, I met a friend who stayed with me briefly in the states, then later with another roommate of his, whom I would later visit with my girlfriend in Shibuya... It was gratifying to not only get there, but to visit with friends I had made from the States...
There's a name on the internet for the types of people that this thread is talking about, it used to be "wapanese", then, "
weeaboo", and now, simply, "wee bee"... As Mike mentioned, I think you'll encounter these people most of all on the internet, it's sort of a safe zone for them, where they can make their grandiose ill-informed ramblings known without fear of getting a follow-up punch in the face.
Perhaps, instead of talking about how most of us already feel about a group of people who want to make a place they've never been to their permanent home, I'll list some warning signs...
A) Basing your ideals of Japanese manhood on Oshare Kei band members, using this to make statements such as "I looooove Japanese men, Myavi is teh love!"
B) Owning any sort of resin ball-jointed doll, like a Dolfie... Dressing your Dolfie up like a J-Rocker earns you additional negative points... Being in a relationship with your Dolfie, having your Dolfie in a relationship with
another Dolfie... etc etc...
C) Eating copious amounts of Pocky, Poccari Sweat, Calips, or any other food generally consumed by Japanese 8 year olds because this makes you feel as if you are integrating into Japanese culture
D) Using what sparse Japanese you know in inappropriate ways, such as speaking to a non-Japanese... random interjections, nonsense... If you use the word kawaii in the middle of an English sentence "Oh, that Super dolfie is soooh Kawaii, I must have it!", you may qualify here...
E) You describe Japanese street culture as either "Gothic Lolita", or "Harajuku Girls"...
F) Regardless of any other opinion, you choose to use any and all things of Japanese origin because they are obviously of superior quality----
G) You re-qualify your own feelings of
pedophilia, and simply label them as "lolicon"... If you have ever refered to a member of a Japanese fan-service idol group (Chase, Berryz, C-ute, Sweets et al...) as "pedolicious", you qualify 188%. If you explain these actions simply because you feel that this is just part of "Japanese culture", subtract some more points...
H) If the majority of bands you listen to have some sort of absurd French sounding name whos members air guitar, & pretend to be bishounen, you just may be....
I) If you have ever typed: ^_______________^ or some equivalent thereof, while being completely earnest....
J) If you've ever added chan or tan to the end of someone's name in a way that is abstracted from the Japanese langauge, "Hey we're all going over to Katie-chan's house to play para para paradise, sugoi ne!?"...
K) If somehow you think that every Japanese street kid drives around all night in drifting competitions...
L) If you think that Japan is a "Western" country, that tries to "copy the West"... not so much negative points, but, slightly mis-informed...
M) If you think that the word "otaku" is some sort of cultural badge of honor...
N) If absolutely every single one of your musical interests involves J-pop, or visual Kei... If you make your friends occasionally listen to these bands even though you know that they despise them, or rather, you choose your friends based on the fact that they are the only ones whom you can crank up Gazette with....
O) If you use roumaji to piece together nonsense Japanese phrases to show people your love of the Japanese language, while still having never actually studied it...
...and so on, and so on, and so on.
ps. I'll say that I had to take a break from my Japanese meet-up class prceisely due to some of the over-zealousness of the members... Even people with very good Japanese language skills (but poor pronunciation) doing their best "irashaimasse" shopkeeper impersonation can unhinge even the most patient among us.
