Four Seasons Hotel Osaka announces the appointment of Gianni Costa as General Manager, ushering in a new chapter of destination-led luxury in one of Japan’s most vibrant cities.
A seasoned leader whose career has spanned some of the world’s finest hotels, from Switzerland and Hong Kong to Bali and Hangzhou, Gianni brings to Osaka a rare combination of operational mastery, global perspective, and a passion for a sense of place. With his arrival, Four Seasons Hotel Osaka renews its commitment to crafting moments that are as singular as the destination they inhabit.
Gianni will lead the team in elevating guest journeys through strengthened local partnerships, highly personalized service, and newly refined immersive experiences – including at the signature GENSUI floor, where Japanese ryokan traditions merge with modern design and thoughtfully curated rituals. Guided by Gianni’s strong background in Food and Beverage, the hotel’s unique culinary offerings will also take center stage, including Sushi omakase reimagined with a subtle French influence, guided by the culinary vision of Yannick Alléno and authentic Cantonese dining at Jiang Nan Chun.
“It’s an honor to welcome guests to such an exceptional property, where location, design, and locally inspired offerings come together to deliver remarkable moments in one of Japan’s most dynamic cities,” says Gianni. “In particular, I’m excited to oversee the evolution of GENSUI, where new enhancements invite travelers to connect more deeply with Osaka while still enjoying the bespoke care and comfort for which Four Seasons is acclaimed worldwide.”
Born in St. Moritz, a celebrated Swiss luxury destination, Gianni grew up surrounded by the art of hospitality. After gaining early experience in some of Switzerland’s finest hotels, including the Dolder Grand Hotel and Baur au Lac in Zurich, he graduated from the prestigious School of Hotel Management Belvoirpark Zürich.
Gianni began his Four Seasons journey in Bangkok in 2006, with his dedication and talent rapidly propelling him through successive roles, including Assistant Director of Food and Beverage in Nevis and Damascus and Director of Food and Beverage in Hong Kong, where he oversaw a vast culinary operation with several Michelin stars – a testament to his meticulous standards and ability to lead teams of the highest caliber. As Resort Manager at Four Seasons Resort Bali at Sayan from 2018 to 2024, he spearheaded multiple initiatives to elevate both guest and employee experiences, contributing to the resort’s Forbes Five Star rating. Most recently, he served as General Manager at Four Seasons Hotel Hangzhou at West Lake, a true gem within the Four Seasons portfolio.
With a career shaped by two decades across iconic Four Seasons properties, Gianni has cultivated a fluency in luxury hospitality that spans borders and cultures – while remaining firmly rooted in local context. Known for his warm, supportive leadership, he sees himself as an enabler, focused on drawing out individual strengths and creating an environment where teams feel empowered to perform at their best.
“At its heart, hospitality is all about people and relationships. When a diverse team embraces this philosophy, united by a genuine desire to make others feel valued, that’s when the magic happens,” shares Gianni. “Along with reaffirming the position of Four Seasons Hotel Osaka as a market leader, my goal is to support the team in crafting exceptional moments of discovery, connection, and immersion for guests – in a way that’s only possible at our hotel.”
