as staying away from big cities
I didn't know there was such a thing as a 'international Illustrated postcard' issued by Japan Post. They also issued the official postcard for the Tokyo2020 Olympics which were already closed, when I get ones I will send them to my friends.
Too late information of the Tokyo2020 postal official items : https://www.japanpost.jp/tokyo2020/stamp/index.html (in Japanese)
I knew that special items were issued for every event, not just the Olympics, and that interesting postmarks were used, but living away from big cities like Tokyo is quite a disadvantage in terms of philately. I enjoyed to visit post offices collecting postmarks called 風景印* with local characteristics when I was living in. Where I live is not a postal hobby friendly place have few unique postmarks. One of the best things about big cities is the abundance of entertainment, which can be expensive though, lol!
