I've been working in the industry in Tokyo for 15 years. And why should we care how everyone else uses the terms if we are professionals? Even the document's title says Automated trading.
It’s not uncommon to take an HFT trade that is competitive in the US or German markets and go around applying it to markets like Tokyo, London, Singapore, Etc. But the converse is not usually as successful.
So if you start in Tokyo, it might be harder to move up and out just due to more restrictive regulatory frameworks and less efficient markets there.
