Japanese for Everyone by Gakken Review
Gakken's single book offering provides a fairly solid grounding for further study, but also gives enough of a base to allow the learner to communicate in a fairly short time.

Pro Very practically focused
The situation in chapter 1 matches most people's first hour of visiting Japan precisely. Although perhaps the grammar explanations are not as strong as other options, the foundation is quite firm for later self studying.
Con No obvious followon for future learning
This is only a single text, not the introductory text of a larger series.
