Yasaka launched Mark V in 1969 and its catalogue says more than ten million have been sold. It is a natural-rubber-based, high-friction rubber that Yasaka still makes in Japan, and it is the rubber Yasaka measures all its others against.

The reference rubber
Yasaka rates its rubbers relative to Mark V, which is set at 10 for speed, spin and control. That makes Mark V the middle of the range by design: the M2 version, for example, is rated Speed 11 with a harder 45–50° sponge, and the HPS version Speed 12. Yasaka's 2019 catalogue says Mark V has been made in the same factory, from the same materials and by the same process since launch.
What to expect
Tabletennis11 describes Mark V as a traditional non-tensor rubber with a grippy topsheet and a medium sponge, giving a more linear response than modern tensors: you get out what you put in. Dandoy lists it as OFF- with medium hardness. That linear feel is why coaches like it for building technique, and why it is durable: Yasaka's 2017 catalogue gives it its top durability rating among its rubbers.
Choosing a thickness
Table Tennis England suggests beginners start on a 1.5 mm sponge. 1.8 mm suits most improving players, and 2.0 mm or max give more speed for stronger attackers. See our sponge hardness guide for how the degrees compare.
Best blades
On an allround blade such as the Stiga Allround Classic it makes a very forgiving first custom bat. Stronger players use it on faster blades for a controlled backhand.
Who it suits
Beginners and improving players building technique, coaches setting up club bats, and anyone who wants a long-lasting, predictable rubber at a low price.
Not the fastest rubber any more, and it does not pretend to be. For control, consistency and value it is still hard to beat.
