"Design a modern and sophisticated line-art logo for a coffee shop inspired by the essence of ‘NEYJER’ using stylized Japanese characters. Feature a sleek coffee cup with angular lines and dynamic steam rising in a fluid motion, suggesting energy and movement. Incorporate minimalist elements such as geometric shapes or subtle accents, like a single, bold coffee bean or abstract waves that suggest freshness. The Japanese characters should be rendered in a stylish, clean font that balances well with the overall design. Aim for a monochromatic or limited color palette to enhance the contemporary feel, creating a striking and memorable logo that appeals to a trendy audience while remaining simple and elegant.
