Short answer: The best whetstone for Japanese knives (beginner) is the King KDS 1000/6000 Combination Whetstone. The stone the sharpening community sends beginners to. The main things to weigh are combination grit, soft and forgiving, soak it, and keep it flat.
King KDS 1000/6000 Combination Whetstone
The stone the sharpening community sends beginners to. The 1000 grit side sets a sharp edge on a dull knife and the 6000 side polishes it to a refined finish, so one stone does the whole job, and King stones are soft and forgiving to learn on. Beginners like that it is affordable, widely recommended, and enough to get a Japanese knife truly sharp.

For a beginner the right first stone is a combination grit that both sharpens a dull edge and refines it. Beginners look for a forgiving medium-and-fine combo stone that soaks easily.
