Well, I haven't seen the program in a while, but I recall that the "walking through a table" effect began with what I believe was Andrew Mayne's "Pocket Sawing in Half"--followed by a cutaway to Aki Hoshino's reaction--then back to Sakai ("Dr. Leon") already walking toward the centre of the table. Of course something dishonest happened in the meantime.
Or maybe there was something else that happened during the program that I've forgotten that makes you question his integrity as a human being?
Japanese tv is rife with programs parading debunked "psychics" like Jucelino Nobrega da Luz as the real thing, informing the gullible masses that he predicted 9-11, the 1995 sarin attack in the Tokyo subway, and certain high-profile murders in Japan.
Television here is poisoned daily with John Edward-esque con artists telling grieving teenagers that their dead boyfriend "is sitting next to you now, telling you not to get married for at least three years" etc etc.
In a place where palm-readers set up shop inside Buddhist Temple grounds to cater to the folks in line, where blood type may determine whether or not one gets a job...
a little camera trick during a tv magic effect means nothing.
Whoop de f**king doo.
