"Mitsubishi's Hyatt code (11657) follows Hyatt's standard corporate verification pattern. FlyerTalk users report 50% ID check rate across Hyatt stays in Asia, mitigated by "self-printed business cards that worked 100% of the time." Mitsubishi is a major Japanese conglomerate with strong presence at Hyatt properties in Tokyo, Osaka, and Singapore. Park Hyatt Tokyo has specific documentation of requiring "badge, business card, and email confirmation" for corporate rates. Hyatt Place/House properties globally: essentially never check."

"I mean, you can book the rate, but 100% PH Tokyo requires proof of employment. I had to email from corp domain and provide a business card (Dec 2022). If you show up and can't provide proof of employment, either you'll be paying a very expensive full price for your stay, or they'll invalidate your reservation."

"I was asking who was eligible to use OUR corporate discount when the GM volunteered this information. Management is way more visible at the (rather small) PHT than at larger Hyatts. I know I'm highly likely to run into the GM or his chief assistant during every stay, especially since I'm usually there for at least a week. Hence, I often hang on to my non-urgent questions until I see them. Might as well hear it from the source!"
