How older was Yoko Shiraki than Joe?

The age of Joe is inferred from the seasons of episodes.

He was 15 years old when he was arrested and 21 at the last fight.

As for detail, read this.

The age of Joe Yabuki – How old was he at that time

Then, how old was Yoko Shiraki?

It is not clarified in “Ashita no Joe."

I try to suppose her age from the few hints in the original comics.

Was Esmeralda Yoko really 16 or 17-year-old?

Nishi explained to Joe about Yoko, when Yoko came to the juvenile training school to play Esmeralda in the charity theater company.

”According to rumors, Yoko Shiraki is a very beautiful girl only 16 or 17-year-old."

I can’t believe it.

Her behavior and way of speaking…

I don’t think she was a teenager.

Yoko drove a car when Rikiishi discharged

Although Rikiishi in the anime series left the juvenile training school by a helicopter, in the original comic, he got out by a car Yoko was driving.

The driver’s license acquisition is impossible for a person younger than 18-year-old in Japan.

It means Yoko was at least 18-year-old at that time.

Since Joe was 16-year-old then, Yoko was 2 years senior to him at least.

Yoko=Joe +2 (+X)

Yoko stood surety for Danpei

Yoko stood surety for Danpei Tange who acted violently in the association of boxing and was arrested.

In Japan, a person under the age of 20 can’t be a surety.

Then she was over 20-year-old at that time.

It was an event that happened on the day after Joe’s release and he was 17 then.

Yoko=Joe+3 (+X)

The lower limit is 3 years older than Joe, how old is the upper limit?

We found that Yoko was 3 or more years senior to Joe.

She was over 18 when she met Joe and over 24 on the title match between Jose Mendoza and Joe Yabuki.

Next, how old was her upper limit?

There is no concrete information on this issue.

Looking at Yoko’s behavior, she can be seen in the 30’s.

Joe mistook Noriko as Yoko

Joe mistook Noriko as Yoko on the first day of his work at Hayashi grocery store.

It seemed to Joe that the two women were very similar.

Noriko was 17 at that time.

If Yoko was 30’s, Joe couldn’t mistake Noriko and Yoko.

I think that it’s possible to mistake a 17-year-old girl and a 20-year-old woman.

17 and 21, 17 and 22…

I guess that “17 and 22" is the limit of mistake in seeing.

The upper limit of the age of Yoko at that time was 22, no matter how older than Joe (17).

 Summary:
Yoko=Joe+3 to Joe+5 (the upper limit is not clear)
