AI Prompt for Japanese Space Conference Poster Design with Futuristic Cityscape

"A polished Japanese event poster in a dramatic, aspirational sci-fi tourism style for {argument name="event year" default="2026"}, vertical layout, rich deep-blue space background blending into a bright daytime cityscape. At the top, outer space with a detailed Earth seen from orbit at upper left, a radiant sun flare at the planet’s edge, dense stars and faint nebulae across the sky. Large bold central Japanese headline text in white with subtle gold accents and a strong drop shadow: 「宇宙科学技術 連合講演会 {argument name="event year" default="2026"}」, with a smaller slogan above reading 「宇宙の未来を、ともに拓く。」. Surrounding the title, exactly 4 space elements: 1 lunar lander descending at left, 1 small satellite with blue solar panels near center-left, 1 larger satellite at upper right, and 1 white rocket launching vertically on the right with bright exhaust and billowing smoke. Add elegant golden orbital swoosh lines circling around the title and spacecraft. Below the title, place a gold badge reading 「宇科連」 and several centered lines of smaller Japanese descriptive text about Japan’s largest academic event for space science and technology, involving space science, JAXA space policy, space development startups, and comprehensive discussions on Japan’s space development strategy. The lower half transitions to a realistic panoramic view of Utsunomiya, Japan, with mountains in the distance and Mount Fuji-like snowy peak visible on the horizon, modern mid-rise city buildings, and a wide tram corridor. Feature a sleek modern yellow-and-black light rail tram prominently in the lower right foreground, angled toward the viewer, glossy reflective windows, destination sign reading 「宇都宮駅東口」, with overhead lines absent for a clean futuristic feel. Near the right midground behind the tram, include a large white satellite dish antenna facility. At the lower left, show a plated serving of exactly 6 golden-brown gyoza dumplings on a white dish with a small soy sauce dipping bowl in front; add a curved red Japanese label on the plate rim reading 「宇都宮餃子」. Near the gyoza and tram, include a circular dark-blue callout with gold trim describing the host city and specialties, with Japanese text indicating 「開催地 宇都宮市」 and noting famous local items: gyoza and the Utsunomiya light rail. Along the bottom, create a structured navy information band with gold and white text. Include exactly 5 major information blocks: 1) date block on the left with Japanese text 「会期 2026年 11月10日(火)〜11月13日(金)」 in large high-contrast type, 2) organizer/sponsor block listing 「主催 JSASS 一般社団法人 日本航空宇宙学会」 and co-host logos/text for JAXA and NICT plus a smaller line for additional participating academic societies and organizations, 3) venue block with Japanese text 「会場 ライトキューブ宇都宮 栃木県宇都宮市宮みらい1-20」 plus a small rectangular inset photo of a modern glass building, 4) a row of exactly 5 icon-labeled topic categories reading 「宇宙科学」「宇宙探査・観測」「宇宙開発ミッション（JAXA等）」「宇宙政策・制度」「宇宙ビジネス・スタートアップ」 with simple white line icons above each label, and 5) a website/QR block at the bottom right with a search-bar style URL area showing a JSASS conference URL, a visible QR code, and a yellow circular sticker saying 「今後の情報をお届け！」. Use clean commercial-poster composition, glossy photorealistic montage, crisp typography, realistic lighting, strong contrast, gold highlight accents, and a premium official event-poster finish."
