Don't you dare bash a company that works hard bringing bands to my country. I don't see how you are the spokesperson for America, and I don't know how you are forming your opinions about the dinner being offensive and it ruining a bands reputation? Are you crazy?! I'm sorry if I sound rude, I'm not trying to be mean, but I think you are a little misguided, and I don't want someone who is misinformed to put ideas into the heads of fans.
First of all, do you realize how much money goes into bringing a band over here? These things don't just happen. JHRE staff has to fly to Japan to meet with the bands to discuss plans before anything is even settled. It costs even more money to bring a band over here once you include their entourage (and then add food, hotel, gas, etc.). Their equipment must also be shipped over. Then you have to consider costs of the venue and/or convention the band is performing at. Now, I know this is just Kamijo coming over, but you do realize this is to see how big the fan turnout is. If a lot of fans come, and they make enough money selling merchandise and doing the photo sessions then the entire band will be back for a tour. The auctions help pay the way for the band members to come here.
The bands have to agree to these events beforehand, so if they felt degraded by doing a dinner in any way they wouldn't have agreed to it in the first place. It's quite the opposite. The bands enjoy the dinner events. They even think of it as a blind date! An uchiage in Japan is one thing, but you even said you end up talking to your friends all night. I would much rather spend money to have an intimate one-on-one dinner with a band than meet a bunch of fans! This way you are actually sitting at the table with the band and able to talk to them all you want. The bands are always happy to meet their fans. After one of the dinners a band member even went up to Harry, gave him a hug, and thanked him for it!
I don't understand why people always have to put a negative spin on everything. This is a good thing for the United States! I am happy that a company like that exists. Otherwise I might never have the opportunity to see these bands unless I actually went to Japan. I'm sure whatever expenses I'm paying towards JHRE are far less than what I would pay for a trip to Japan! I don't even think $50 is that outrageous for a dinner with a band! I understand it is an auction, so the price can be greater than that, but sometimes they sell for under $100. When you deduct the cost of the meal you have, it really isn't that much, and I'd be happy to help out the band in any way I could even if it means spending a little extra money! (^_^)
Edit: I just checked Jhouse-Rock's website and it doesn't actually state whether it's going to be an auctioned off dinner, so it's always possible that it's going to be a banquet event where you will be in a ballroom at a convention center. That means there will be lots of other fans.
