Japan has restarted at least 14 reactors.

Or even just Wikipedia:
"As of January 2022 there are 33 operable reactors in Japan, of which 12 reactors are currently operating.[87] Additionally, 5 reactors have been approved for restart and further 8 have restart applications under review."

Your ourworldindata links says nothing about current investments. It is therefore not a repudiation of what I wrote about investments in nuclear and renewables.
Here's what ChatGPT says:
Is the industrialized world massively investing in both nuclear energy and renewables?
ChatGPT said:
Yes — there is strong evidence that in many (though not all) of the industrialized world, there is a massive investment push in both renewables (especially solar and wind) and nuclear, though the balance, pace, and scale differ a lot by region. Below are key takeaways, some of the caveats, and what seems likely going forward.
Nuclear energy
Interest in building new nuclear capacity has increased. Many countries are extending the life of existing reactors, and new reactors are under construction. For example: 63 nuclear reactors globally are under construction as of 2025, representing over 70 GW of capacity.
Annual investment in nuclear (both in building new reactors and extending existing ones) has risen by almost 50% since 2020, now exceeding USD 60 billion per year. (IEA)
Some countries are making major new commitments: UK’s investment in the Sizewell C plant, public & private funds for modular reactors, Canadian incentives for SMRs, etc.
Research indicates that global nuclear capacity might more than double by 2050 (from ~398 GW now to ~860 GW).
It says clearly about the respective parts of renewables and nuclear in Japan gridpower, before and after Fukushima (which happened 14 years ago).
If a sustainable massive and very quick restart of such heavy industrial equipment seems possible to you after 14 years I stay alert, popcorn in hand.
Sizewell C seems a good deal to the UK because it will in practice the French taxpayer will have to pay for it. Let's see if it happens, or even will be possible. SMRs are an investment-luring ghost ready to explode: https://www.hackerneue.com/item?id=45182003
Sure, there will be some new reactors. Most will be built horrendously over budget and late, obtaining refined uranium and managing their waste will be a growing concern, will produce electricity at a high cost not compensated by any benefit as other ways to compensate 'intermittency' will be more and more effective, any incident will threaten the depreciation of investments, the decommission costs will skyrocket (see nuclear decommissions in the UK, right now)... Good luck with this!
My bet: in 40 years the nuclear industry of nations which expand it now what coal industry is to Germany.
> the entire industrialized world is investing massively in both nuclear and renewables
Nope: https://ourworldindata.org/grapher/electricity-fossil-renewa...
