~ A high-efficiency customer attraction strategy where homebuyers come in saying "I saw it on ○○!" and a product/design strategy that is specifically requested with "I want to build with Harbor!" ~ In an era where simply creating a "good house" is not enough to survive, the environment surrounding local construction companies is becoming more challenging than ever due to rising material costs, labor shortages, and intensified competition with major companies. In this context, Harbor House, which has been established for 19 years in the fiercely competitive Niigata Prefecture, has achieved an annual completion of 450 houses and is now ranked number one in the number of construction starts in Niigata Prefecture. Its strength lies not in a single charismatic leader, but in a thoroughly refined "system." Customers who say, "I came after seeing your website" are reliably guided to contracts through a highly efficient sales flow based on "batting average management." In this online seminar, we will generously share the know-how of customer attraction, product, and management practices that Harbor House implements with business owners. We will present the shortest route to becoming a "construction company that continues to be chosen" in your business area. ◇ Detailed information and application https://x.gd/pUe2b ◇ Phone inquiries TEL: 025-383-8881

The demonstration showcases a variety of AI solutions, including AI-equipped PCs, workstations, the Japanese facial AI avatar "Aine," digital assistants, the compact desktop "Dell Pro Max with GB10" (equipped with NVIDIA GB10), rack-mounted solutions, and conference audio equipment. Digital assistants are already being implemented across a wide range of fields, including finance, healthcare, government agencies, and local municipalities, with expanding applications in marketing, customer service, and operational efficiency. This exhibition provides a valuable opportunity to directly see how "Aine" can contribute to solving business challenges.

"Connecting technology and field knowledge to accelerate implementation" We provide a space to co-create "solutions that can be used from tomorrow" by merging real challenges from the field with cutting-edge digital technologies (spatial, ground, DX), going beyond mere technology demonstrations. 【Event Overview】 Date: June 5, 2026 (Friday) Main session 13:30–17:30 Networking event: 17:45–19:45 Format: Akihabara Hall (3 Kanda Neribeicho, Chiyoda-ku, Tokyo) or Zoom webinar Expected attendees: 200 people Speakers: International Kogyo Co., Ltd. / Texar Co., Ltd. / Just Co., Ltd. / Toshiba Lighting & Technology Corporation / Ground Network Holdings Co., Ltd. / Nihon University College of Science and Technology, Department of Architecture Special website for the conference:
