Ocean or sea; also associated with continuous improvement.
Kaisen is a modern name with multiple potential roots. In a Japanese context, it is often associated with 'Kaizen', a philosophy of continuous improvement, or can be derived from kanji meaning 'ocean' and 'fresh'. In English-speaking regions, it is frequently chosen as a modern rhythmic invention following the popular 'K' and '-en' naming trends.
