What is the max monthly investment you can make in T-NISA?

[Oliver]

I was investing in the 2023 T-NISA 33,000 yen and now I want to try to max out my 2024 T-NISA but I am unclear as to what is the max monthly investment allowance.
Is it 1,200,000 divided by 12 months?
100,000 yen a month?

¥300,000 (¥100,000 in the tsumitate portion)
