Monospace font that supports both English and Japanese [migrated]

I'm looking for a monospaced font that supports both English and Japanese. All characters should be the same width (since it's monospace).

I haven't found anything that works from looking on the internet. Google has created a font called Noto Mono, a monospace version of their font family Noto, which is supposed to support all languages. However, the English and Japanese characters are different widths here too.
