There are indeed some linguists who propose broader language families that Japanese may be part of, including relations as mentioned in the video with Korean and Austronesian languages. And there is even an attempt to find a common ancestry between these languages and the Turkic language family - based on similar grammar structures and such - but the evidence is sorely lacking, and ... we may never know. This hypothetical family is called "Altaic" It's possible, but these hypotheses are more likely to be wrong than right.

Ryukyuan languages are related to Japanese, so it's not a "lonely" language.

@@sertaki The Altaic hypothesis is most likely right, because languages don't just appear out of nowhere, they always have an origin somewhere. But proving any connections at that kind of circumstances is very difficult, so it'll likely just stay as a hypothesis. Yet just logically thinking, what else Japanese could be but an Altaic language? At least the languages of this proposed group are the most similar to Japanese out of all the neighbors.

​@@user-zu3wq3lf3h There is not enough evidence to claim that it is "most likely" right. It's certainly possible and convincing arguments can be made, but we simply do not have enough old texts to re-create a Proto-Altaic language that convincingly explains the evolution of Turkic languages from it as well as Korean, Japanese and all the others that are included in there by its proponents. It is just as likely (actually, more so - because of the lack of evidence) that these two families are fully distinct and simply share grammar rules. Extraordinary claims like this require good evidence. A similar situation: Basque. The language has been claimed to be part of different families again and again, but there was never conclusive evidence given, sometimes the evidence was even flat out wrong (like using words that came into both Basque and Georgian as loanwords from other sources as a upport by claiming they are cognates derived from a common ancestor) and was based around political ideology primarily, with the (supposed) facts being presented in whatever light best supported the idea. For all we know today, Basque is simply the only surviving sub-branch of a larger family hat was replaced by Indo-European languages when these took root in Europe. Attempts to restructure language relationships or what counts as a dialect vs a language and similar issues are very often political in nature, and it helps to think about who or which ideology is being supported by such ideas - if they are not based in scientific fact. Also, languages might in fact appear out of nowhere, we do not know. It is unclear whether all languages go back to one common ancestor tens of thousands of years ago, or if they developed independently. But even if they do share an ancestor from before humanity left Africa, it would be unprovable - there is no surviving evidence, and hypothesizing about this is not very useful in the greater picture, as there is such extreme diversity in languages and so much change through the ages in grammar, phonology and vocabulary, that any "Proto-Human" language would be unrecognizable in comparison to any modern ones. And Japan was certainly quite isolated for a long period of time, China had already been active on the global scale before when Japan was still in the "Jômon" era, which was effectively still a stone age-like society - up to around the year 300 BCE, when some people from Asia arrived and changed up language, culture and ethnicity in Japan. And yes, Japanese is not a true language isolate, since there are a few other small languages in the Japonic family which spread across the islands of Ryukyu/Okinawa (which are very much endangered). But outside of these, there is only hypotheses, once you start trying to create a line between Turkic, Mongolic, Tunguscic, Japonic, Koreanic, Ainu, you get into interesting thought experiments and ideas, but there simply is not enough proof.

Japanese is not the only language isolate, think of Basque for example

I wish you good luck with your Japanese language journey. 日本語の勉強がんばって！

がんばって！

Good luck😄. By the way, i hope my channel can help a bit😊.. I'm be glad to help!!頑張ってね
