Adding on to this: The National Diet Library of Japan has a lot of very well digitised resources. They can be a bit annoying to get to but they are there. NDL

Adding on to this: The National Diet Library of Japan has a lot of very well digitised resources. They can be a bit annoying to get to but they are there. NDL Digital Collections: https://dl.ndl.go.jp/ https://dl.ndl.go.jp/ NDL Image Bank: https://ndlsearch.ndl.go.jp/en/imagebank https://ndlsearch.ndl.go.jp/en/imagebank If you view items in the image bank, they show you a preview. You'll then have to click the link that takes you to the digital collections page for that item (which shows the full uncropped image). From there you will want to scroll down to the download panel and make sure you select "high resolution". Those images are generally at least around 2k x 2k or better depending on when they were captured. You should also be able to get the unconverted image from their api (as many of them are in varying, less common formats like JP2/JPEG2000) but I haven't been able to figure out how. If you sent someone at the library an email you could probably figure it out though.
