Vote counting is underway, and NHK's decision desk says the ruling coalition will comfortably maintain control of the Upper House. We are projecting that Prime Minister Shinzo Abe's Liberal Democratic Party and its junior partner, Komeito, will take more than half of the seats that are up for grabs this election.
The traditional celebrations are already underway for some LDP members.
There's also still a chance that the coalition and lawmakers in favor of amending the Constitution could continue to hold two-thirds of the house -- a key benchmark for a possible amendment process.
We are still waiting to see if the largest opposition, the Constitutional Democratic Party of Japan can make major gains by expanding its pre-election force.
And now to our projections in more detail.
The ruling coalition has secured a total of 130 seats in the Upper Chamber... maintaining its majority.
While the opposition camp has secured a total of 86 seats.
That includes their uncontested seats, which you can see here represented in lighter red and blue.
Let's take a closer look at the ruling coalition.
The LDP and Komeito are projected to add 60 to their 70 combined, uncontested seats... bringing their total to 130.
Tonight, we're also talking about the debate on amending the Constitution.
The ruling coalition, and Nippon Ishin, which is also in favor of the move have secured a total of 67 in this election.
Two-thirds support is needed in both houses to put a Constitutional amendment proposal to a national referendum.
As you can see, it's still short of that important 164 seat benchmark.
