$21 for comparable GaN 70W w/o the retractable cable.
Voltage is what's most important, not wattage. The hair dryer must be able to accept 240v.

It is not because "they had lower Wattage in a lot of places" or "use different wattage around the world" – I'm not even sure what that means. Outlets in Japan are 100V, and use a similar two-prong plug, though there are a few with a third grounding plug similar to what is in the US.
Info about electricity in Japan: https://www.japan-guide.com/e/e2225.html
A US hairdryer will work in Japan by just plugging it into a regular outlet, though the output will be slightly less powerful due to the lower Voltage.
Be aware that this travel adapter does NOT have a Voltage converter so it will not run appliances (such as hair dryers, electric toothbrushes and shavers that only work on 110/120V). Except it does have the converter for the USB plugs.
Most electronic chargers, e.g., for your phone, tablet, laptop, games, etc., will work on 100-240V connections. You can just plug them directly into the wall outlet, as long as you have the correct adapter. You can usually buy adapters that fit your US plug and the local outlet at your foreign location for about dollar or two, so you really don't need an expensive "universal" adapter. Just bring your regular chargers and get a cheap adapter when you arrive.
EDIT: If you still would like a "Universal" travel adapter, this previous SD deal at $9 may be a better deal: https://slickdeals.net/f/18476359-reflex-power-universal-international-travel-adapter-gan-charger-35w-pd-fast-charger-plug-2-usb-a-2-usb-c-ports-quick-charging-suitable-for-europe-usa-austral-8-99-fs-prime?src=SDSea
Yes, Wattage does matter, and what is displayed in the answer you received by Chat GPT about the Wattage limit of a Voltage converter you use (some will be limited to only 50-100W, for electronics, and others can handle the up to 1875W of a hair dryer), shows it can be a problem anywhere--if it exceeds the capacity of the wiring or converter, and this is not limited to Japan or any particular country.
Also, yes, the line current that the wiring in a house or hotel has a limit and if it has a 15A breaker on 100V and you're running your hair dryer on high heat at 1875W and there are other high Wattage appliances on the same line, it could trip the breaker.
It's not a matter of proving what I said is wrong (and lol-ing over it), A US hairdryer will work in Japan--unless you blow the circuit breaker--but that has nothing to do with being in Japan. It has to do with using a greater load than what the circuit breaker can handle and that can happen in the US or anywhere else.
I think what you are describing is that in places where you tried to use your hair dryer in Japan, they had limits in how much power an appliance you could use on that circuit, and not that your hair dryer would not work at all. Unless you meant that you plugged it in, turned it on high and it tripped the circuit breaker.
Did you plug in your hair dryer and it would not work at all? Or were there signs saying you could not use hair dryers on the circuit?
