In all the so called whistle blower and pseudo dissidents in the whole USA so far there is not a single one i can see as truly awake with good intention, all are seliing something or working for the enemy.
On my other site that is online since 2022 we are 67 members and less than 10 active members but we have only interesting and stimulating content and we have some very interesting live discussion.
For me, I don't mind hot and humid. I'm not a fan of winter though, and Japan housing has very poor insulation. In short, I don't want to be in Japan during any month when it is still cold. (An exception might be Sapporo which has well-insulated homes, I heard).
So for me, April/May/June, perhaps? Although I'm technically fine for any summer month. I do like that the beach culture starts June 1st, I believe. No one goes to the beach until the specific day, which I think is June 1st. So I'd want to be in Japan for that.
