Japanese Civil Code Article 177 Infographic

Goal: Create a dense Japanese legal-study infographic summarizing Civil Code Article 177 and the requirements for asserting real-estate property-right changes against third parties, in the style of a law exam cram-school summary sheet. Use the main Japanese headline {argument name="headline text" default="【民法177条】不動産物権変動の対抗要件 ①誰が「第三者」か"} and subtitle {argument name="subtitle text" default="先に契約した方ではなく、先に登記した方が勝つ"}. Canvas: Square 1:1 image, dark charcoal/black background, high-contrast white Japanese text, thin white panel borders, red/yellow/blue accent colors, compact but readable typography. Make it look like a polished Obsidian-style study note converted into an infographic. Layout: Use exactly 5 major horizontal zones. Zone 1 is the top title bar. Zone 2 is a large transaction diagram. Zone 3 is a three-column explanation grid. Zone 4 is a red judgment-summary banner. Zone 5 is a bottom row of four checklist cards. Zone 1 — Title: Place the headline in large bold white text across the top, with the yellow subtitle centered underneath. Zone 2 — Main diagram: Create one large bordered diagram labeled {argument name="main diagram label" default="二重譲渡"}. Show A as the seller on the left, a circular node labeled registration in the center, and two buyers on the right: B as first buyer and C as second buyer. Include exactly 3 solid white arrows: A to B, A to C, and registration toward B. Include exactly 2 dashed arrows with red question marks implying disputed direction. Add a red note below stating that arrows stretch in two directions and the side that obtains registration wins. Include a small dashed vertical relationship between B and C labeled adversarial relationship. Zone 3 — Three-column explanation grid: Create exactly 8 bordered information panels in this middle area. Left column has 4 panels: a blue-title panel for article text and basics, a yellow-title panel for a 30-second strategy summary, a blue-title decision-standard table, and a blue-title terminology panel. Middle column has 3 panels: a blue-title panel explaining the meaning of “third party” under Article 177 with a red emphasis sentence, a blue table listing third-party types, and a small illegitimate occupant diagram with A seller, B buyer, C illegal occupant plus a yellow Supreme Court note. Right column has 1 large stacked panel area containing three subpanels: a red-title panel about bad-faith possessors and movable property comparison, a reverse-less-than diagram subpanel, and a comparison table of real estate versus movables plus a small list of four delivery types. Keep these as visually distinct cards even within the right column. Visible panel count requirement: The infographic must show exactly 12 discrete bordered cards or boxes total: 1 main top diagram, 4 left-column study cards, 3 middle-column study cards, 3 right-column study cards, and 1 bottom judgment-summary region. The bottom region contains 4 separate checklist cards inside it. Key text content: Use Japanese legal-study wording throughout. Important visible phrases should include Civil Code Article 177, third party, double transfer, registration, simple bad-faith party, faithless bad-faith party, illegal occupant, no-rights holder, successive transfer, and comparison with movable property Article 178. The red emphasis statement should communicate that simple bad faith still counts as a third party regardless of good or bad faith. The main conclusion should communicate that the decisive pattern is whether the two parties are in an adversarial relationship and whether registration is required. Tables and discrete elements: Include exactly 2 main tables in the center/left columns: one decision-standard table with 2 rows and one third-party-type table with 5 rows. Include exactly 1 real-estate-versus-movable-property comparison table on the right. Include exactly 4 delivery-type items listed at the lower right. Include exactly 4 bottom checklist cards with green check icons: simple bad-faith party counts as third party, faithless bad-faith party is excluded, illegal occupant/no-rights holder/successive transfer do not require registration, and registration defects should be written in the answer. Visual style: Dense Japanese exam-prep infographic, crisp vector layout, white thin borders, blue section tabs, yellow highlight boxes, red warning accents, green check marks, small arrows and schematic boxes. Use a compact sans-serif Japanese font, sharp edges, no illustrations of people, no photos, no watermark. Constraints: Keep the entire design legible despite being information-dense. Use consistent alignment, equal margins, and clear hierarchy. Do not add extra decorative icons beyond arrows, check marks, question marks, and small diagram boxes. The color palette should stay black, white, blue, yellow, red, and green.
