I found a conversation on Twitter about an Amazing Race sighting in The Philippines. It's in Filipino (Tagalog?) and I've tried to use a Google translation, but it's not very good. Hopefully someone around here can do a better translation:

Google translates the above as

It could be a local race. My first thought was Final Adventure, the TAR South Korean version, but I have my doubts that Andrew Wolff would be a part of that. Some research showed that Andrew Wolff was the winner of the Mr. Philippines 2012 pageant and 1st runner up in the Mr. World 2012 contest. He also is a member of the 2013 Philippines Volcanoes World Cup Sevens Rugby team. Still, the Philippines is a likely place for Final Adventure to visit since they are staying fairly close to South Korea.
The tweets mention Gumaca, which is Quezon province. Gumaca was founded in 1582 and has a lot of Spanish Colonial buildings. It does seem like the sort of place an Amazing Race version would visit. The question is which one?
I thought Chuchu Yamaha could be a name, but a search didn't bring up any minor celebrities with that name.
