Japan's Emperor Is Stepping Down Soon, Which Could Cause Major Headaches for Computer Calendars

For most people, resigning from your job doesn’t necessitate the invention of any new computer characters, just a new Twitter bio. But as The Guardian reports, when Emperor Akihito, Japan’s current ruler, abdicates the Chrysanthemum Throne next year, that’s exactly what the country will need. Currently, there’s no computer character available to represent the next era on the Japanese calendar, which will honor current Crown Prince Naruhito, and it’ll be a tricky feat of scheduling to create one in time.


While Japan does use the Gregorian calendar, the Japanese calendar additionally keeps track of time using an era name representing the current emperor. In Akihito’s case, his January 1989 coronation rang in the Heisei era (we’re currently living in Heisei 30). The era indicating Naruhito’s reign, however, hasn’t been announced yet, making it especially difficult to create a kanji character representing the name.

It might not sound like a big deal, but for the Unicode Consortium, the organization responsible for establishing standards when it comes to displaying text (and emoji) on devices around the globe, it means extra work on their end to accommodate the nonexistent era character, referred to as U+32FF by the organization. The current Heisei era character is “㍻,” or U+337B. From The Guardian:

Unicode needs to set the standard for that new character. But it can’t do that until it knows what it’s called, and it won’t know that until late February at best. Unfortunately, version 12 of Unicode is due to come out in early March, which means it needs to be finished before then, and can’t be delayed.

The bad timing means Unicode may have to update the scheduled version 12 release with a smaller 12.1 release.

That smaller update will still create major headaches for the organization, as noted by Unicode Consortium technical director Ken Whistler in a planning memo about the character in question. “The characters encoded for these calendrical symbols in Unicode have compatibility decompositions, and those decompositions depend on the actual name chosen for the era,” Whistler wrote. “Because the decomposition, once assigned, is immutable, involving Unicode normalization, the UTC cannot afford to make any mistakes here, nor can it just guess and release the code point early.”

Since major Unicode releases are resource intensive, according to Whistler, his proposal suggests some serious planning, as well as a more narrow focus compared to other minor releases. “This is a lot to chew on, but I think the UTC will be far better off going into this will a specific plan in hand, rather than just reacting in crisis mode once the new era name is announced next year right around the time of the Unicode 12.0 release,” wrote Whistler.

Fun fact: Akihito is the son of Hirohito who ruled from 1926 until his death in 1989. In an interview about his long reign he was asked about WWII. He responded [paraphrasing]: “Oh yes, the war was a terrible mistake.”

The Japanese people were taught that the emperor is a living god, but Hirohito claimed he never believed that. He said he had to agree to wage war or he would be overthrown and killed in a coup d’état and the war would happen anyway. He publicly renounced his divinity after Japan’s defeat.

My own personal Hirohito: my father was an NCO in the Army during the war serving as a surgical technician and medical administrator in the Pacific. He was in Tokyo right after the surrender, and at one point the emperor got sick and had to be transported to a hospital. My dad dispatched the ambulance to pick him up. True story.
