Are Japanese dialects disappearing? The closest answer is that older forms are fading, but dialects themselves are not disappearing everywhere at once.
Compared with the past, more people use standard Japanese. Television, YouTube, and other media expose people to speech from across the country, and it is common to leave one’s hometown for school or work. In some regions, younger people rarely use certain old dialect words that were perfectly normal for their grandparents.
The degree of change, however, varies greatly from one region to another. There are still places where young people speak with a strong local dialect, so it would be misleading to say that all of Japan is gradually replacing dialects with standard Japanese. In some areas, conversations between local people can still sound very different from standard speech.
A dialect is also more than a collection of special words. Even when older vocabulary disappears, regional features often remain in sentence endings, intonation, rhythm, and the rise and fall of the voice. Someone may think they are speaking almost entirely standard Japanese, while a person from another prefecture can still roughly tell where they are from. Sometimes the dialect survives more strongly in the way something is said than in the words themselves.
Many Japanese people also switch between dialect and standard Japanese depending on who they are speaking to. They may naturally use dialect with family members and hometown friends, but move closer to standard Japanese when talking with people from other regions or in a work setting. This does not necessarily mean they have abandoned their dialect. It is more like adjusting the way they speak to fit the situation.
Dialects can also be closely tied to regional identity. Kansai dialect, for example, has a particularly strong presence throughout Japan, and many people from the region continue to sound distinctly Kansai even after moving elsewhere. There is even a familiar impression in Japan that, somehow, Kansai people seem to carry their dialect with them wherever they go. That is not true of everyone, of course, but it shows how strongly speech can be connected to a sense of where someone comes from.
Japanese dialects are therefore not being preserved exactly as they were in the past. Older words disappear, dialects mix with standard Japanese, and the way people use them changes. Yet regional speech continues to survive in accents, endings, and the way people switch between local and standard forms. Rather than simply disappearing, Japanese dialects are changing while remaining very much alive.
