The site is in Japanese.
It says the fast traxx will go 12mph, and it sells for $39 USD
If you click one of the buttons (check out) close to the price it will eventually ask you to register with the site in English. so you can become a Rakuten member.
I did not register, so I do not know if they ship to the states, or how much they will charge for shipping.
Seems like they are just a distribution center for Taiyo toys. Taiyo currently only produces the fast traxx and the Typhoon from the old tyco line up.
