Which emerging Rugby nations do you see growing and challenging for the Top 10 rankings in the next decade or more?

So, was thinking about the 2019 and 2023 RWC. In both cases, we had so called "upsets" and Tier 2 nations like Japan and Fiji making the World Cup quarterfinals.

Now, while Japan has faded badly since the 2019 heyday, Fiji are still flying high. They have the cracked the Top Ten rankings table and have enough talent to compete well in future World Cups as well. The only problem I see with Fiji is their economic weakness and small population, which will challenge future sustainability both in terms of financial and on-field performance.

However, Rugby is showing strong signs of growth in South America and Europe.

With that in mind, which emerging Rugby nations do you see growing and challenging for the Top 10 rankings in the next decade or more?

I am very disappointed with the World Rugby Nations Championship not having promotion / relegation until 2030. IMO, It is a regressive move by WR. However, with the ongoing growth I am still optimistic about new markets emerging and breaking the Top 10 stranglehold among the usual nations, just like Fiji has, when promotion / relegation eventually does open up in 2030.
