Galapagos Protocol in Japan, Japanese calendar and half-width kana

he other day, I happened to learn about a service that discloses immigration records, so I immediately applied. According to my memory, i have traveled abroad more than 100 times, so I wanted to check it out. There was also some professional interest in how they manage data. The procedure was analog as usual, and it took one month from the time of application, but he received the document without any problems. Although the data items are not completely described for each time, I was relieved that they seemed to be recorded accurately as long as I followed the dates. i was strangely impressed with the impression that immigration and data management were surprisingly well done.
Well, the chase. As I watched, I noticed something strange. I looked closely at each document and found out. It's a date display. The cover page is in the Japanese calendar of Reiwa 5, and the contents of the questionnaire are in the Western calendar. It seems that immigration records, which are likely to involve information exchange with foreign countries, have been displayed in the Western calendar for more than 30 years, but the cover page "Regarding the Decision to Disclose Retained Personal Information (Notice)" clearly shows the Japanese calendar. And yet, the seal is carefully stamped. The title is also confusing, but I was a little surprised that the seal is still Showa era generation era in the Japanese calendar. In that case, Amanojaku, who was full of curiosity, decided to check the Western calendar and Japanese calendar with the information at hand to see what else was going on. The result is oops. The passport is in the Western calendar (of course). The driver's license is based on the Japanese calendar. My number card is mysterious and his date of birth is the Japanese calendar and the expiration date is the Western calendar. What the hell is this! So I turned my attention to social security and insurance. Pension records are based on the Japanese calendar only, and Meiji Life, a major Japanese private life insurance company, politely writes the Western calendar together with the Japanese calendar in parentheses. Foreign-affiliated Prudential only uses the Western calendar. Next is the bank. First, the main bank SMBC. The passbook is in the Japanese calendar, and the Internet banking is in the Western calendar. Mizuho is all Western calendar. Local bank use the Japanese calendar. I've done my best up to this point.I want to say, "Digital Agency, do something about it." Including the half-width kana problem, if it is not resolved quickly, it will continue to hinder efficiency, lead to economic loss, and eventually accelerate the decline of national power through the deepening of the Galapagos. I haven't seen any research on how much the Japanese calendar and half-width kana are hindering efficiency, but it must be quite a big deal. On the user side, the input procedure is troublesome and input errors occur frequently. On the supply side, the burden of data maintenance and cleansing has increased and the use of big data AI is a stumbling block. Extra program development, testing, and maintenance that add no value on the system side and are a performance burden. Foreigners must be confused. Just imagining it is a horrifying burden. It is bad that we retain pod protocl designed when semiconductors were one of thousands or tens of thousands of times less than today. It is negligence to use history and tradition as an excuse to not seek a fundamental solution to the problem of the Japanese calendar. There is no future if you run away from familiar and big problems. Let's clean up the data infrastructure before we do the arrogant DX lecture.
