On October 22, 2025, a company anniversary celebration was held in the main building of Kobe Portopia Hotel, in the elegant Ōwada banquet hall. Among the hotel’s many distinguished venues, Ōwada is especially popular for its stately interior design and soaring ceilings, making it a favored choice for corporate receptions and formal ceremonies. Under warm red-and-gold lighting that gracefully enveloped the room, BanMusic Artist Agency presented the accordion duo “461 Montblanc,” delivering a live performance reminiscent of a scene from a French film.
