Japanese crossword «Eutamias sibiricus»

I had to really visualize how adding certain long numbers to a boarder would effect other places. Like if the 8 in the far right column was placed at the very top right, it would impact the 12 right next to it because of the 2 in the top row but that can't be allowed because the 8 already solves a 1 in the row right below it. If the 8 was in the top right, it would then break the 1 clue in row 2 so there is an 'X' in the top right square. You can then work down and find the 8 cant fit in the top 3 rows because of this same logic. Then it again doesn't work in the top 10 rows because of the 1 clue in row 11, the 12 clue in column 24 really restricts where the 8 can go. I needed this kind of logic many times throughout. Hopefully I explained it alright.

As L17L6363 said, you can start from the right and continue at the bottom.
Then you can fill several points in the grid using the basic logic for exemple with the column 3.
When I was stuck, I had one black case in line 2. It could be the 4. Then I tried the column starting with 6 from the top. If it stars from the top it make the column to the left 1-0-1-0, it is impossible because it could be 1-0-2-0. Thanks to that, I could put an X. Then everything became easier. I wish it heps.
