Not a lot of Tungsten in VToku actually, you get about a 1% carbide volume and the only kind of carbides in the steel. Maxamet has a lot more but it's not as big of a deal as far as wear resistance as many think, the real benefit of Tungsten is more in hot/red hot hardness and hardenability.
VToku is a good steel, super easy to sharpen and takes a cool patina, but isn't impressive for wear resistance. HAP40 is a better wear resistant option for Japanese non stainless laminated steels.
For really high wear resistant steel, look to Vanadium and Niobium carbides first. This is why S110V has such extreme wear resistance, it has 3.5% Niobium and 9% vanadium with a huge amount of carbon to bond with and form carbides. Even very small amounts (0.5% even) of V and Nb form carbides.
On a second tier, Chromium and molybdenum are also carbide formers. Only super high carbon/chromium steels like ZDP189 display very high wear resistance. In outright abrasive wear resistance, ZDP is likely on par with Maxamet and S110V as well.
