As far as I know, the Japanese erected at least 2 Japanese-type letter boxes in Hong Kong.
According to South China Sunday Morning Post (10 April 1956), there was a Japanese letter box at the Junction of Dundas Street and Nathan Road. It was replaced in 1956.
And I found a picture taken in 1951, at the mentioned junction, I cannot see any letter box there. Maybe it was blocked by the building. [Update: that photo was of a different location.]
The second Japanese-type letter box I found in a newspaper article located in Kai Tak Airfield, was a wall box (The China Mail, 8 March 1949).
Unfortunately, there were still no pictures of those Japanese-type letter boxes. Do you guys have more pictures of the above locations or information about the Japanese-type letter boxes? Thank you for your help!
Adding photo
Hi Aaron, and welcome to Gwulo.
I noticed your new post was showing an error message. It happened because you pasted images directly into the text, which the new website can't handle. (The website has just been upgraded, so there are still some bugs to be fixed.)
The solution is to first upload your photos, using https://gwulo.com/media/add/image
Then edit the post above, put the cursor where you want to insert the photo, click the 'Insert from Media Library' button, select the photo, and click the 'Insert selected' button/
Let me know if you have any problems getting that to work.
Regards, David
Re: China Mail Article
Appreciate if you could provide a date to the China Mail article. Thanks.
Problems solved
Thank you for your help!
Soy Street
The photo you posted apparently shows the junction with Soy Street and Nathan Road, not Dundas St. It has already been uploaded here. The building on the corner is the Nathan Theatre: https://gwulo.com/media/27736
Thank you!
I was misled by the description in the picture. Thank you for correction!
I've deleted the Soy Street…
I've deleted the extra Soy Street photo to avoid duplicates, and updated the main text above.
Hedda Morrison has a good photo of Kai Tak from 1946-7.
The copy on the Harvard website is sharper (http://id.lib.harvard.edu/via/olvwork364580/catalog), but unfortunately I can't see any sign of a postbox.
