The official site for the remake of Submersion of Japan has been updated to include some early teaser trailers for the big budget feature. At present, there are three adverts on the site, two of which are very short TV spots while the third is a much more extended web only version. It should be noted that the special effects have not gone into the post-production stage, so effects like CGI and other elements have not been added to the footage as of yet. The exception is the single, underwater, shot of the cityscape, which is also the only footage featured in the two TV spots.
