Buddhism in Japan is notoriously corrupt in many ways.
From the payment for blessings, to the giving of Buddhist names for funerals (the longer the more expensive -- but the more Buddhist!), to a slew of other 'scams' of sorts, Buddhist monks/priests in Japan rake in the money. I'm not saying that all priests are bad folk, and I'm not saying that there are folks who genuinely believe in, and practice, the eightfold path. I'm just saying I've never met them.
My first experience with a Japanese monk was about 4 months after I got here. I was sitting in my local bar where I practiced Japanese, and knew nobody, so I started chatting up the couple next to me (as I still had the 'FOB' interesting-foreigner scent on me, rather than the 'piss-off' vibe I apparently give off now). I asked the man what his job was, and he said, 'bou-san' which I didn't understand. So I asked him what that meant, and he explained that he worked in the next town at the temple. So I exclaimed, 'bo-san?!' and he told me to shuttup, seeing as how he was sitting next to a girl, in a bar, drinking liquor, and smoking.
I have since met priests who have had to quit liquor due to their livers being about ready to give out, priests who used their monk-status to go to the US to give lectures (and make good money doing it), as well as a slew of other monks who used their job to allow them to live the easy-life.
Though in all fairness, I think I should share a Buddhist Koan that is semi on-topic...
I have to paraphrase, unfortunately, because I can't find where I snagged it from...
A Buddhist monk hired some men to dig a new outhouse for the temple, as the old one had to be filled in because of the smell. Upon digging out a new hole behind the temple, the men hired to dig it found some fish bones. Regretting having to tell the head monk that there were priests eating bones in the temple, they came heads hung low to tell him, "Sir, we're sorry to tell you this, but while digging a new hole, we found fish bones buried -- it appears that one of your priests has been eating fish!"
The head monk turns to him and says, "That's horrible! In my day, we ate the bones too!"
The point being that no monk is perfect. It's part of the Mahayana 'can't get enlightened in this lifetime' drawbacks. The question is just whether or not the current generation of monks have taken it too far (I'd argue yes).
