I would like to politely reply no.
The reason I disagree is because I think Wu Xia is its own unique genre with heavy emphasis on stunning martial arts choreography, tropes, and narratives primarily set in China than special effects. They can still have special effects as much as they want, but that is not the prime focus of that genre.

Tokusatsu on the other hand is best described I think as a special effects-heavy live action film/TV media genre rooted in the aspects and methods of Japanese special effects film production.
And I think limiting to Japan-only is wrong because despite not being from Japan stuff like France Five, Battle Strike Team: Giant Saver series, Legend Hero are toku technically just to name a few.

It would be like saying chow mein and zarusoba are the same thing because they are categorized under noodles, when really they are not considering their origins and the way they are prepped, served, and eaten.
