Yes, it's likely to be that. But couldn't they hire a Jap interpreter? Fans in Europe aren't all fluent in English either, nobody would look down on them if they spoke funny. Plus Toshi speaks decent English. He even came to Japan Expo with Yoshiki once, but never showed up in Europe anymore. Maybe he doesn't like airplanes? Or maybe he doesn't like Europe, why.
As for Yoshiki never resting, I think his management might play a role. With the album being postponed a kazillion times, they're probably afraid the international fan community will dwindle and utimately forget about them. Say, around 2006, this forum was SUPER active, they even did a huge meetup in Paris when one of their world tour concerts got postoned. There were japs, americans, frenchies, brits, people from iceland, you name it. People from all over the world were posting pics of their X tattoos on the Pictures of you thread. We were all here in 2008, live streaming the reunion concerts and commenting every single song. Toshi's voice was terrible on the first night. Yoshiki collapsed midway through and some crazy dude here was saying he had been confirmed dead by the jap press. Most of us called it bullshit but the chat room here went bonkers. People were already preparing a gathering for his funeral. I was 17 at the time and that guy was a big deal to me so I shed a tear too. I remember the rush of joy when I saw him opening the second night's concert at the piano in a red shirt. It was 6 am and I hadn't slept that night. OMG OMG guys he isn't ded! It was super funny.
Those were great times. It was like an X lan party when they streamed lives. Does anyone have a new mirror? was the golden line. We knew everything about what they were doing backstage by stalking the Myspace accounts of staff and assistants and we had a blast trying to figure out whether or nor this random figure in the background was Taiji. Or whose girlfriend the random model could be. Or why Sugizo had named his kid such a funny name. I went on a long hiatus and when I came back, 10 years later, the community had shrunk considerably. Only the die-hard fans remain. The kind of fans that will cross Europe just to see Yoshiki at a random joint eating a burger (well, more like doing a We Are X premiere, but you get the point). His travelling to meet fans in person here and there are his way of keeping the community alive, IMO. Nobody sticks that long (at least not in full-blow fanboy/girl mode) if a band hasn't released an album in 20+ years. It's a shame. I miss the old days so bad.
