How do you spell hi in japan?
こんにちは : 'konnichiwa' is Japanese standard/common daytime
greeting and closest equivalent to 'hello, hi'. More informally and
in spoken language only, it can change to 'konnichi' or 'konchi',
being closer to 'hi, what's up, etc'. A very colloquial and
masculine term for casual greeting would be おっす : 'ossu'.
