So when did you realize that Mr. Tojamura was actually Catherine Martel?  I was a kid when I first watched this, so I honestly didn't know until the moment she revealed herself to Pete.  I remember thinking, "Why are all of these Asian people suddenly showing up in Twin Peaks?".  And then being overjoyed to finally realize that Catherine was alive and getting her revenge!  

But watching it now, I kind of think it's a great disguise... strange, yes, but that's TP for you.  And given that the role was actually attributed to a fictional actor in the credits, there's even less reason to believe it's a costume.  I wonder if I would have been able to tell it was Catherine sooner had I watched the show first as an adult.  What do ya'll think? 

I never knew it was Catherine until it was revealed... However, I thought he was rather odd, like if he was an american actor with awful asian makeup. I must admit I was shocked in that "Dummy, it's me!" scene...

right away -from the standoff with Ben Horne.  But as soon as she was checking in, talking to Louie,  the side shot and posture was totally Piper Laurie -and i remember jumping up and down at the Twin Peaks party, "That's Catherine!!"

I found out when the show officially revealed it to me.

Sadly for me I was more suspicious that it was Catherine, because I don't have seen the show in english but in french, and they keep the same voice double except that she try to talk with a huge voice (but failed imo), it was already a strong possibility that it was Catherine, despite that I was not sure at 100%.

I thought it was a hilarious scene when it was revealed, but at the same time I was pissed as I hated Catherine in season 1, and she didn't seem to change in season 2.

I never knew it was Catherine until it was revealed... However, I thought he was rather odd, like if he was an american actor with awful asian makeup. I must admit I was shocked in that "Dummy, it's me!" scene...

 Couldnt have put it better myself, Gordon!  I never thought it was Catherine, but i knew something wasnt quite right with the guy.  I remember me and my friends watching it, and collectivly we were all like "Hell No!"  lol

Watching it today, I can kind of tell that Mr. Tojamura is packing some boobies.  I didn't know about trannies back in the day...

I didn't no 'till the very end... and in the scene where it was revealed I immediately

thought the scene of Pete and Mr. Tojamuras small talk, Pete offering milk and everything,

I just had to laugh and think, how Twin Peaks was that!
