Monster Zero x SciFi Japan - Archive Only

A quick rundown of Godzilla DVDs that feature Japanese dialogue with subtitles:

Gojira
Godzilla Raids Again
Mothra vs. Godzilla
Godzilla vs. The Sea Monster
Son of Godzilla
Godzilla vs. Hedorah
Godzilla vs. Gigan
Godzilla vs. Mechagodzilla
Godzilla vs. Mechagodzilla II
Godzilla vs. Megaguirus
Godzilla, Mothra, and King Ghidorah
Godzilla Against Mechagodzilla
Godzilla: Tokyo S.O.S.
Godzilla Final Wars

All the rest are either English-only, or not released on DVD in the US. You can get GRA and Mothra vs. Godzilla from Classic Media's site at www.godzillaondvd.com and the others at www.deepdiscountdvd.com which is currently having a 20% off sale through Saturday, if you use a coupon code (like SUPERSALE).

I would recommend the following:

Gojira: http://www.deepdiscountdvd.com/dvd.cfm?itemID=SON084559

7-Pack (Spacegodzilla, Destroyah, King Ghidorah, Mothra, 2000, Megaguirus, GMK, Against MG): http://www.deepdiscountdvd.com/dvd.cfm?itemID=COL005772

3-Pack (Son of Godzilla, Mechagodzilla, Tokyo S.O.S.): http://www.deepdiscountdvd.com/dvd.cfm?itemID=COL009004

Godzilla Final Wars: http://www.deepdiscountdvd.com/dvd.cfm?itemID=COL012761

Well, technically, all the Sony releases have the International onscreen text, no Japanese. But aside from that they're completely uncut and have the Japanese tracks.
