Goro, meaning the 'fifth' brother, was 'born' in 1962. Of all the Aizawa large robots, Goro was the first to be popularised by the Western press.
During the recent restoration of Aizawa's robots, another robot, incorrectly I believe, is now being called Goro.
Source: Popular Mechanics, Feb 1965 p 131. Aizawa incorrectly called Sagami. Note also the row of lamps around his waist not seen in other photos. Light/dark colour scheme is slightly different, particularly around the feet, and the antennae shape is difficult to identify as the same. Possibly this is a variant or an upgrade.
The above caption suggests that Goro was born in 1961, all other dates give 1962, although most press dates are from 1964.

Electronic Baby-Sitter
Keeping an Eye on Junior a Cinch With This Redoubtable Robot
HAVING a tough time keeping your eye on Junior? Is he always getting into your cabinet under the kitchen sink? Messing things up the instant your back is turned?
Well, you can solve your problem electronically these days if you wish. All you need is $8,310 –plus shipping charges, Inventor Jiro Aizawa, 60, of Hoyamachi, Japan, has the answer to a harassed housewife's prayer and his name is Goro and that's what it cost to make him.
The latter, a highly developed robot, has a firm grip on things—a steely grasp of the situation at hand that would keep Junior in hand at all times. The way-out electronic baby-sitter could increase a parent's range of discipline considerably, for it is controlled by radio waves as far off as 300 yards.
On command, Goro can walk forward and backward, turn around, go shopping (that should make a big hit with Mother, too, on super-market days), and talk through a built-in radio. He weighs a formidable 271 pounds.
All in all, Junior had better mend his manners. Any day now his ingenious invenor, who has been working on robots for 32 years, may decide to add spanking to Goro's accomplishments.

Robot Built By Institute Seeking New Toy Ideas
TOKYO (UPI)—A Japanese Inventor has come up with a toy robot that's bigger than life.
And scarier. The robot is run by radio from a distance of up to 300 yards. But despite aerials on his shoulders, a radar screen on his head, electrode buttons on his back and volt and ampere meters on his vest, he doesn't frighten children away. They love holding his hand despite his iron grip.
The robot's name is Goro, which means "fifth child" in Japanese. Goro has four older brothers and one younger, all brought into the world by a 60 year-old inventor, Jiro Aizawa.
Goro stands five feet five and weighs 271 pounds. He can walk forward and backward, turn around, do his own shopping, talk through a built-in radio and even wink at the girls—or at least blink.
He has yet to carry bags for passengers at Tokyo Internatíonal Airport, a feat accomplished by one of his brothers. The only thing Japanese about Goro is that he does not shake hands when meeting friends; he bows.
The main problem in building Goro, his inventor says, was to find a way to keep him upright. The problem was solved by extra heavy feet, which are nearly 24 inches long.
Goro's inventor has a research institute in Hoyamachi, west of Tokyo, dedicated to the production of new toy ideas. The institute receives an annual subsidy of 50 million yen($138,500).
The Institute provides 280 Japanesee toy manufacturers with designs for toys sold in England, France, Germany, Italy, Monaco, Switzerland and the United States as well as Japan. Aizawa's
next project, now on the drawing boards, is an electronic robot that will respond to whistle signals.
Goro, however, is not for sale probably because it cost $8,310 to build him.
