Minimalist vertical Japanese tattoo design for inner forearm…

Minimalist vertical Japanese tattoo design for inner forearm featuring the kanji "改善" (Kaizen). The calligraphy is elegant, balanced, and slightly soft brush style, not too aggressive. The composition is clean and breathable, with plenty of negative space. Add a few delicate sakura petals gently falling around the kanji, very subtle and minimal. Optional thin enso circle (zen brush circle) lightly behind or partially enclosing the kanji. Black ink only or with extremely subtle faded grey shading. No clutter, no heavy elements, calm and harmonious, traditional Japanese zen aesthetic, tattoo stencil ready.
