From 1969, this pack of cards provides English translation and pronunciation of Japanese phrases. Each card is unique, whilst each suit has a different focus – hearts on general interaction, clubs are about getting around, diamonds help with shopping, and spades with hotels and restaurants:

All the cards have the same back:
Here’s an example, one of only a couple that mention Citizen watches directly:
The pack also includes a world time card:

Wow, Stephen! Where do you keep finding these treasures?!
Best regards,
Jay.
Hi Jay – found these on Yahoo Japan,
All the best,

Hi Stephen,
Ah, that magical auction site! I’m a frequent lurker there myself but I’ve never come across 8110s! There’s a bigger selection on eBay!
Regards.
Jay.
Hi Jay, it’s interesting that there aren’t many 8110s on Yahoo Japan, and some of them are not correct either. Mind you there’s an incorrect example in the Museum Book of Japanese Watches!!
