I did my #年賀状 [Nengajyō, Japanese New Year's greetings] this year using Riosanatea. It's a Python program that can parse a CSV list of Japanese addresses and print them correctly on the 年賀状 blanks from the post office. The spacing and everything was fairly simple compared to the 年賀状 software (Mac) and mail merge (Office/Pages) I've used before. A big win for #foss software!
I'm running #linux, I guess you can run this on Win/Mac also as it's just Python.
