Boogie woogie pianist Brendan Kavanagh, who goes by the name Dr K, shared a video of the moment the group told him to stop filming their faces during his livestream.
After the musician was accused of touching one of the women - an allegation he strongly denies - British Transport Police officers asked him not to upload the clip to YouTube.
On Wednesday night, a spokesman for the station said this was due to maintenance works in the main concourse of St Pancras International.
She added: “The Elton John piano has been relocated a few metres outside of the cordoned off area and remains open for public use.
“Once maintenance works are complete, the piano will be moved back to its usual position.”
On Tuesday, Mr Kavanagh said of the removal: “You can't make this stuff up.
“The station have cordoned off the piano and put two guards either side.”
The tourists, who were holding flags of the People’s Republic of China, can be seen standing at the back of the video when Mr Kavanagh starts playing.
They quickly confronted the pianist, asking if their faces were visible, before demanding Kavanagh stopped.
When approached by police, Mr Kavanagh said: “Listen, we’re in Britain, we’re in a public space, it’s a free country.”
However, one of the women involved hit back at the piano blogger, accusing him of provoking them by referring to them as Japanese instead of Chinese, playing a “discriminatory” song and constantly telling them: “We live in Britain, not in China”.
She claimed they had been waiting to play the piano themselves for a Chinese New Year greetings video filmed at the station.
They asked Mr Kavanagh to stop filming them after they realised he was livestreaming.
The woman alleged: “We kept waiting for over 40 minutes. He still played the piano for a long time.
“When I approached him his assistant kept filming and this was when I realised he was probably a content creator filming videos. But I didn’t know he was live streaming at the time.
“So I asked can he delete his video because our content today is non-disclosable.
“It can’t be made public in advance. He kept asking me questions and I really didn’t know how to respond.”
