Basic Japanese lessons imply writing and reading Hiranaga
and for beginners it's quite hard remember all of them in a
short period of time. Knowing that memorization cards can
speedup I tried to find some and the closest best match I
found on polarcloud. Some improvements that I needed
were a larger kana on the front side, a small kana on the
back to avoid unnecessary flipping, higher font quality, no
redundant text on the cards.
For the cards I used LaTeX CJK packages, pdflatex,
flashcards package, data from unicode.org, vim and a few
python and bash help scripts. The pdf files are released under

Best printed on A4 cardboard (280g/m2), with no margin or no
page scaling, at a print center, if possible. Most printers
will not be able to print the grid about 2mm from each edge
but thats all right, the grid is just a guide for cutting.
Ask at the print center if they can cut your cards precisely
by the grid, if not, cut them by yourself. The kana on the last
page are repeated to save paper when printing even number of sets.
Update: attached pdf files without grid.
