Featured Of all the things I’ve seen stamped on the back of a pendant.....

.....I never expected to see ‘Sewerage Bureau Tokyo’!
All google gives me is the expected poo related results.....
It’s c1.5cm diameter and I haven’t looked closely at the glass yet as I’m out and haven’t got the right glasses!
Anyone any ideas I’d be intrigued to hear them.
Thankyou

 

I certainly never expected to see it on the back of a piece of jewellery, in English.

 

Expat employee of the month token?

 

You don't suppose that brown is from a Tokyo sewer?

 

Perish the thought. Pleeease!

 

I really don’t think I want to know....but I do because it’s so odd

 

Now that is truly bizarre!

 

That I hadn’t considered! Maybe a tourist souvenir to remind you of your visit to the Tokyo Sewerage gift shop

 

I had to buy it for 50p because I couldn’t quite believe my eyes.

 

On everyone's bucket list no doubt.

 

Maybe it came from here........ https://www.tokyocreative.com/sights/3293-museum-of-sewerage

 

At the risk of being PinC, only in Japan. Probably the correct answer, though.

 

Think this is the best contender so far!

 

Want to help me write the eBay listing?!

Had a look under a loupe and it looks like blue glass with quite slot of bubbles with a browner area towards the centre .I don't know, maybe it's better if it holds onto its secrets!

 

OH TOO FUNNY !!! ...

 

The museum's site says part of their mission is to emphasize the importance of clean water, so maybe blue glass with bubbles is about water. The brown part we won't discuss.
