Worth checking
Check the official rate: free MGH Rewards Club membership publishes a 5% member discount at Mitsui Garden Hotel Toyosu PREMIER.
A human reviewer observed an English registration route, international-format address fields, country-code phone guidance, and no Kana/Furigana field. Final submission, account creation, SMS, and server-side acceptance were not tested. Eligible direct stays also earn Bronze members 5% in points after checkout, while OTA and travel-agency reservations do not earn those points. Coupon and ReFa offer booking/stay periods are unknown, so they are excluded from this rating and verdict.
