It has been talked about for years that the plan was eventually to dump much of the stored nuclear wastewater into the sea, more than 1 million tons of treated wastewater from the Fukushima power plant.
They are running out of room for storage and something eventually was going to have to be done.
Scientists have been working for years on what options there might be for storage solutions, it had to be dealt with.
Eventually to get rid of it discussions prompted ideas of whether they should be burying it, or dumping it into the ocean etc, a variety of options were considered over the years. This is one move they've been doing and talking about for years now, dumping the waste into the ocean.
We knew it was coming but that doesn't mean they haven't faced public backlash over it.
Officials have urged the public that this is not going to pose any threat to the people or surrounding area.
It has been a waste management nightmare for them
Dumping it into the ocean is also likely to be the cheapest and fastest option for them as well.
Since making those announcements on the plans there have been protesters who have reportedly rallied outside government offices to express their discontent with the decision.
