I’ve built and used the Tokyo rigs and they work. I bought the long stem swivels from China and I like them because it allows the lure to rotate 360 degrees with little resistance and a little better action without line twist. I actually make mine with ear ring stops to hold the weight where I want it for different purposes and so I can change weights as needed quickly without having to bend the wire ends. It also allows the weights to pull off if snagged.
