Japanese Self-Help Book 3D Mockup

A realistic 3D product mockup of a Japanese softcover book standing upright at a slight angle on a seamless off-white background, revealing both the front cover and the spine. Clean studio lighting with soft ground contact shadows. The cover features a minimalist, serene illustration of a white arched doorway opening to a bright pastel sunrise over a calm sea, with a woman in a flowing white dress standing in the archway looking toward the horizon. Large, elegant vertical Japanese text in a Mincho serif font frames the archway, reading "[我慢をやめたら、人生が動き出した。]". In the top left corner, smaller horizontal text reads "[自分の人生を取り戻す 7つのステップ]". The bottom third of the book is wrapped in a light pink promotional belly band (obi) featuring a prominent horizontal catchphrase reading "[もう、他人軸で生きなくていい。]", small subtext separated by a dotted line, and a white circular badge on the right with a small crown icon reading "[累計 20万部 突破!]". At the bottom of the band are 4 small rectangular keyword boxes followed by "Everything will change!". The white spine displays the title, subtitle, author, and publisher placeholders.
