I think you might be confusing the Rokkasho Reprocessing Plant (not yet operational, intended for plutonium extraction from spent fuel) and the Rokkasho Uranium Enrichment plant, which has been running at 75 tSWU/year (I think that should be kSWU or tSW) since 2023-08-24 https://www.jnfl.co.jp/ja/business/about/uran/daily/enrichme... 112.5 tSWU/year since 2025-06-26 https://www.jnfl.co.jp/ja/business/about/uran/daily/enrichme... and 150 tSWU/year since 2025-11-20 https://www.jnfl.co.jp/ja/business/about/uran/daily/enrichme...

It's a bit weird though that they have a graph of tons of uranium hexafluoride shipped that shows the last shipment in 2018 and nothing since then.
