1.
the classic approach, the standard, the mainstream
The most typical, orthodox, or universally accepted way of doing something. In modern Japanese, often used to describe what is considered the definitive or quintessential example of something.
2.
royal road, easy path, shortcut
From the expression "there is no royal road to learning" — a supposed easy shortcut to mastery. Often used in the negative (王道はない) to mean there are no shortcuts.
Usage
Sense 1 is the dominant modern usage: 王道 as "the classic, orthodox, or standard" version of something. It carries a positive nuance — the 王道 approach is tried and true. Common in reviews, food discussions, and pop culture.
Sense 2 comes from the proverb 学問に王道なし ("there is no royal road to learning," attributed to Euclid). In this sense, 王道 means an easy shortcut, and is almost always used in the negative.
