和気藹藹
wa.ki.ai.ai

Literally: harmony – spirit / mood – harmonize / flourishing – harmonize / flourishing

Alternately: Full of serenity and stillness. Overflowing with tranquility. Congenial. People getting along well together.

Notes: 和気 is a feeling of harmony; 藹藹 is the state of being calm, of having a quiet mind. The latter half can be written with the doubling sign, as 藹々, or replaced with 藹然 (aizen), “hovering like mist or clouds,” “gentle,” “calm.” However, replacing it with 愛愛 is an error.

Sometimes you’re required to achieve 和気藹藹 before they let you out of the meeting? Harmonious business talks seemed to be a common theme in image search results.
