20th Anniversary Festival
~A story of SPA＆HOTEL MAIHAMA EURASIA, walking with Eurasia-wan~
On September 27, 2026, SPA＆HOTEL MAIHAMA EURASIA will celebrate its 20th anniversary.
We have been supported by all of you for the past 20 years. Drawing strength from that experience and your kind words, we renovated our spa area on January 15th of this year, and have continued to evolve to deliver a new form of relaxation. And we will continue to do so—next year, the year after, and into the future beyond.
SPA＆HOTEL MAIHAMA EURASIA will continue to be a place of extraordinary healing that you'll want to return to, and we will not be afraid of change, as we strive to create an even more comfortable space.
SPA＆HOTEL MAIHAMA EURASIA 's 20th anniversary event is an anniversary festival filled with surprises and excitement, themed around the "journey of memories" embodied in its logo. Over the course of a month, we will be holding special events where you can enjoy a variety of experiences, including a jumbo gacha machine, gender-reversible baths, special accommodation plans, limited-time restaurant menus, and a Yurashiwan photo spot, celebrating the 20-year story we've shared with our official character, "Yurashiwan."
20th Anniversary Logo
For the past 20 years of SPA＆HOTEL MAIHAMA EURASIA, the official character "Eurasia-wan" has always been there, watching over and walking alongside it. This logo represents that journey as a "path of memories."
The film-inspired design reflects our desire to look back on the precious time we've spent with our customers so far and to connect that story to the future.
Jumbo Gacha Lottery
A giant gacha machine is coming to SPA＆HOTEL MAIHAMA EURASIA! As a special event to express our gratitude for our 20th anniversary, we have prepared an exciting raffle event that everyone can enjoy. Guests staying during the eligible period (excluding children sharing a bed) will receive one giant gacha participation ticket per person at the front desk.
