Honestly, not much in the way of alternatives. Tritium is very, very difficult to remove from water. Basically the only option, aside from discharge, is to store it in tanks and wait for enough half lives to elapse that the tritium effectively just decays away on its own. The half life of tritium is just over 12 years, so that'll still be a while longer, and that gets expensive (in terms of both storage costs and space costs). However, tritium is not particularly dangerous, especially at low concentrations.
As usual with radioactive liquids, dilution is the solution. And Japan has diluted this liquid to 1500Bq/liter, far short of their internal legal limit of 60,000Bq/liter, and even far below the WHO limit of 10,000Bq/liter.

It's been 12 years, 5 months, how much longer are we talking about?
Usually to consider radioactive sources "gone" you have to wait at least 5 half lives (which makes it 99.875% gone), which would be 60 years in this case.
Honestly, that's probably why they're getting ready to discharge the tritiated liquid now.
12 years? Holy shit that's insanely fast. Can you even go near that stuff, nevermind release it into the ocean?
As the saying goes: The solution to pollution is dilution.
Good! About damn time. Tritium isn't dangerous when diluted in the ocean, which contains 4.5 BILLION TONS of uranium naturally.
Have they considered the kaiju implications of this?
I think… maybe Japan wants one ?
They'd have a national crisis to justify country-wide emergency production of giant robots...
In WWII the US processed Ocean water to get the same radioactive components, and now Japan wants to put them back.
This seems like Godzilla's origin story. Should be fun.
