Biwako Otsu Prince Hotel (4-7-7 Niohama, Otsu City, Shiga Prefecture; General Manager: Takayuki Nakayama) is running a special Silver Week plan at Lake View Dining Biona (37F) from September 19 (Sat) to 23 (Wed, holiday), 2026: families of three generations or more dining together for lunch or dinner buffet get one child under 7 free for every two adults.
With growing interest in "three-generation travel" and "three-generation dining out" as occasions for family gatherings, the hotel has timed this plan to Silver Week, when families come together. At Lake View Dining Biona, guests can take in sweeping views of Lake Biwa from the 37th floor while enjoying a buffet built around Shiga's local ingredients. The lunch buffet features Japanese, Western, and Chinese dishes made with lake fish and seasonal autumn vegetables, offering a taste of autumn in Omi. The dinner buffet showcases Shiga's prized brand ingredients — Omi beef, Kurao pork, Omi chicken, and Omi duck — alongside local specialties such as Yakisaba Somen (grilled mackerel over somen noodles) and Amenoiyo Gohan (rice cooked with a trout unique to Lake Biwa), taking guests on a food journey around Shiga.
Through a shared meal that sparks conversation across generations, the hotel hopes to create a lively gathering space and memorable moments that deepen family bonds against the backdrop of Lake Biwa this Silver Week.
