Within the next decade or so, how likely is it that Japan will be accepting more immigrants?

Question:

They have a very low rate right now, will this look to ever change in the near future?

Answer:

Do you mean when will Japan accept more unskilled immigrants?

Japan already accepts skilled immigrants.

It's a very low rate right now because Japan simply at the moment doesn't need many unskilled immigrants, so in the near future it is unlikely.

People keep asking this question like you, simply put, if you were in Japan's position, would you open the flood gates?

Japan's immigration policy is actually pretty rational if you look at it objectively. Japan isn't like the United States, which is a country built upon immigration. The United States like it or not, needs those immigrants (both legal and illegal) to work as a country, Japan at the moment does not.
