The alternate arranged, glossy dark green, odd pinnate leaves have a length of 10 to 30 centimeters and consist of nine to 13 leaflets. The elongated, ganzrandigen leaflets are 2 to 6 inches long.

The flowering period is mainly between early to mid- spring. The early flowering of Japanese wisteria can be problematic in a temperate climate, as early frost can destroy the knospigen inflorescences. In addition, it blooms only after passing through the youth stage, which can take many years from the same genus as the Chinese Wisteria.

The fragrant, decorative, hermaphrodite, zygomorphic flowers are five-fold and 1.5 to 2.0 inches long. The five sepals are unequal. The five petals are depending on the variety violet to blue or white. The flag is large and repulsed. The wings are sickle-shaped. The wings are not attached to the boat.
