The standard/formal way to emphasize in Japanese is with bōten "side dots":

However, there is no easy way to enter or display these online, hence hacks like spacing.

data:text/html,<div style="font:16px monospace; text-emphasis:red filled circle">Hello World
Unfortunately it doesn't seem to be supported in Chrome yet.
data:text/html, <textarea style="font-size: 1.5em; width: 100%; height: 100%; border: none; outline: none; font-family:monospace" autofocus />

When you land on a site with a delayed paywall, you can copy out the content just before the popup, and then paste it into <body contenteditable> to view at your own leisure.
Hey Unicode Consortium, where you at?
It would still be a problem of IME and font support.
On input, there's already so many shortcuts and hacks (e.g. SHIFT/CAPS is already taken to force switch from hiragana to katakana) that it's hard to imagine some natural combination that could be memorized.
On the font side, there's already the battle raging for having proper jp fonts in smarphones instead of the chinese ones, so additional support for marginal features is an uphill battle to say the least.
