Aside: I love the design of Japanese websites. They're high-density, extremely legible and clear and perhaps the only bad part is that a lot of headers are actually images, not sure why.

If this was done in silicon valley, it would be a horrendously wasteful page with scroll jacking, large amounts of negative space, huge padding, magenta/purple gradients, unnecessary animations, massive fonts, and would take 50% CPU usage, 836 MB of ram to load after 20 seconds. If you're running Firefox on Linux machine, it would crash it.
