Tenga, a manufacturer of the world’s most popular sex toys merchandise, conducted the most comprehensive study to date using 500,000 males from around the globe, measuring their penis size, and comparing them.
And boy it was a surprise.

A popular myth that asians aren’t really as “endowed” as the rest of us has been shattered to smithereens. They actually rank higher than americans (can’t help but think of all those porn movies with huge guys. None of them was asian. This is about to change soon.) The average length of a Japanese male’s erection is 13.56 centimeters (5.33 inches), with a diameter of 3.53 cm (1.39“) at the head and 3.19 cm (1.25”) at the shaft, writes Tokyo Reporter.

The statistic places Japanese males 10th worldwide, behind — among others — France, Australia, Italy, even Thailand, which according to Tenga boasts the largest penises in Asia. But what the Tokyo Reporter was especially astonished about is that Japan placed ahead of the United States, which ranks 11th, with an average of 12.9 cm (5.08“).
India and Thailand and Cambodia go head to head (to head), each coming in at a solid 4 inches. China’s little soldiers, ranking 4.3 inches on average, are a good match for the average Japanese Capt. Winkie (also 4.3). But the real weenies seem to be in the Congo (7.1 inches), with Ecuador not far behind (6.9 inches).
On the other side of the great penile divide were South Koreans, whose average of 9.6 cm (3.78”) made them the shortest among males in the 17 Asian countries for which measurements were available.
