Postmark of the Tokyo Post Office Memorial Stamp
In 1870 (1870), Mitsuru Maejima, who was later appointed Minister of Posts and Telecommunications, drafted a postal system and traveled to the UK in the same year to inspect the postal system of developed countries. Immediately after returning to Japan, we started establishing a modern postal system, and in 1871 we started postal services between Tokyo and Osaka using post offices, post boxes, and stamps.
The current Nihonbashi Post Office is a memorial place for the start of the modern postal system. Introducing the monument of "The Birthplace of Postal Mail".

This is a portrait in honor of the establishment of the postal system. I've always respected you.
Postmark of commemorative stamp at Nihonbashi Post Office
In the past, when stamps were collected, it became popular to say "first day cover" and have them postmarked on the stamp.
It's a nice postmark of Nihonbashi Post Office. When I purchased stamps and postcards of 63 yen or more, I was asked at the counter and pushed.
If you ask for a seal on Nihonbashi souvenirs and letters to a distant friend, I think the recipients will be pleased.
