Simple Japanese expressions

If you need to communicate to Japanese (but do not know the words), these may be useful.
Of course, following 5 words may be more pivotal:
Thank you = arigato,
Excuse me = shitsurei shimasu,
Hello = kon nichiwa,
Good-bye = sayonara,  and
Good to meet you = hajime mashite

Japanese, a, i, u, e, o, ought to be pronounciated always as a, i, u, e, o.
Not to be pronounciated as ei, ai, you, ∧, i:, ou etc.
Repeat twice is must.
These may not be authentic, but are surely understandable.
