OK, Cure Rock Radio is a 24 hour broadcast of J-rock music, but they have a couple of shows(Mae is actually not there anymore, because she was offered a record deal in Japan, so I don't know about the accuracy of the schedule anymore, but they DO still have the talk show on Tuesday's). Here's a link to the schedule, and obviously, you have to click on "Listen Live":
CureUSA - PURE J-ROCK
And then there's Tainted Reality. I don't know if they're 24 hours as well, because I only listen to the show they give at 8:00 on Thursdays and Incognito on Saturdays(Incognito is about recent and not well known bands). Here's a schedule for TRR:
Tainted Reality
Anyway, I don't know if you'll like any of these. but I will suggest the GazettE, DELUHI, Matenrou Opera, exist+trace, Dir en Grey, DIO-distraught overlord, UnsraW, Acid Black Cherry, Heavensdust, AND(that's the name of the band), D'espairsray, and there's a Power Metal band from Osaka called Galneryus that sings mostly in English
If you like any of these, a few of them have music available at the US iTunes store. Also, if you like any of the stuff you hear on Cure Rock Radio, one of the DJs(Shion)has a poll at the forum of what band most people want to see on this side of the planet; you can pick two, and he has another thread where you write your top 5 favorite bands for the same purpose. He intends to send this information to the bands' management, and the bands themselves may see this, so check it out if you're interested:
