guidance, orientation session, briefing
An informational session or set of instructions given to introduce people to a new course, program, workplace, or system.

- 入社ガイダンス: new employee orientation
Usage
For general advice or guidance in an ongoing sense, the Japanese word 指導 or 案内 is more appropriate.
