Resolve garbled Japanese characters in matplotlib of Jupyter Notebook on Docker
Introduction
Every time I use jupyter in various environments, I feel that I am suffering from the problem of garbled Japanese characters. This time there was no solution for Don Pisha, so I will record it.
Overview
Resolve garbled Japanese characters in matplotlib of Jupyter Notebook on Docker. (Proceed by adding to the Dockerfile.)

work
1. Check the location of the font file
Confirmed on jupyter.
import matplotlib.font_manager as fm
fm.findSystemFonts()
['/ File storage PATH / Somehow .ttf', You should see something like'/ file storage PATH / something .ttf']. (Use in 3)
2. Font download
Download "IPAex Gothic" from IPAex Font. Put ipaexg.ttf in the same directory as Dockerfile.
3. Place the font file in the confirmed location
Added to Dockerfile.
COPY ipaexg.ttf /File storage PATH (check with 1)/
4. Check the location of the matplotlib configuration file
Confirmed on jupyter.
import matplotlib
matplotlib.matplotlib_fname()
You should see something like'/ settings storage PATH / matplotlib / matplotlibrc'. (Use in 5)
5. Set the matplotlib font
Added to Dockerfile.
RUN echo 'font.family : IPAexGothic' >> /Setting storage PATH/matplotlib/matplotlibrc
6. Check cache location
Confirmed on jupyter.
import matplotlib as mpl
mpl.get_configdir()
You should see something like'/ cache PATH / .cache / matplotlib'. (Used in 6)
7. Delete cache
!rm -r /Cache storage PATH/.cache/matplotlib
end
