The 'Marry the Night' singer, who arrived in Tokyo earlier this week, will remain in the country through the holiday and plans to share a meal with some of her Japanese fans.
"Well I'll be in Japan right up until Christmas day," GaGa told MTV News.
"So I'll be eating with all my Japanese 'little monsters'. I like shabu-shabu (a Japanese hot pot dish)."
GaGa also posted a tweet on Wednesday morning (December 21) which read: "Sipping tea in Japan with Haus. Feeling so grateful. We sold about 1 million albums a month worldwide since the release of Born This Way."
Lady GaGa was recently voted 'Most Overrated Act' in Billboard's year-end music poll, beating Britney Spears and Justin Bieber.
The star's Facebook and Twitter pages were hit this week by a phishing scam after hackers staged a fake iPad giveaway contest .
