Rob Fitts (on his blog that is no longer officially on-line but can be seen at the Wayback Machine Internet Archive) listed six Japanese cards of Berra. Three of these are from 1953 - probably produced as a promotion for the MLB tour. I don't have any of these cards but they were sold in recent years by Prestige Collectibles Auctions and I've swiped their images here:
|1953 Yamakatsu JBR 27|
|1953 Uncatalogued Bromide|
|1953 Uncatalogued Color Bromide|
Rob mentions two other cards from the 1950's. I think the post I've linked to showed one of them but unfortunately the image did not get archived with the blog post. The other is a "colorful menko card". I believe that both of these cards are uncatalogued.
The final Japanese Berra card is the only one that I actually own. A US serviceman named Ed Broder did a number of home brew Japanese sets in the mid 1970's (Broder's son Rob became famous/infamous for producing unlicensed MLB cards in the late 1980's). One of his sets commemorates the Mets tour of Japan in late 1974 and includes this card of Berra:
It's hard to tell but this photo (as well as those in the rest of the set) were actually taken during the tour in Japan.
