Jrock is the short version for "Japanese rock", which includes Visual Kei, normal and alternative rock, but from Japanese bands. The term sometimes includes Japanese metal bands (such as Maximum the Hormone), but it's more rarely seen.
The most popular Jrock band in Japan is SID, but the GazettE has a lot of fans outside the country. They play Visual Kei and DOES plays normal rock in Japanese.

Term used to describe Japanese rock music. As far as I know, this term is actually rarely used in Japan; most use the term "J-POP" instead. Many groups that are referred to as "J-Rock" also fall into the category of Visual Kei (for example, Luna Sea, Malice Mizer, Gackt, Moi Dix Mois, Nightmare, and others). A major element in Visual Kei is flamboyant, eccentric, and feminine (less common nowadays) costumes. To be driven away by "freakiness" of many of these groups is very foolish, as one would miss out on a beautiful form of music

J-rock is 'japanese rock' but shortened. It is basically rock music from japan. J-rock has progressed over the years, and now some j-rock albums you are now able to get in the USA more easier than before.

Most j-rock bands are found out over the internet, or animes. For instance, the j-rock band FLOW does the opening song for the anime Eureka Seven, The Pillows did the ending song for the anime FLCL, and Asian Kung-Fu Generation did several opening songs for the anime FullMetal Alchemist, all making the bands more popular and well-known throughout the USA.

Some people think j-rock is in it's own genre, but it is NOT it's own seperate genre of music. J-rock is just used to tell you the music is from Japan.
One popular j-rock band is Dir En Grey.
