jpn.config in langdata/jpn is loading jpn_vert as a sublanguage
tessedit_load_sublangs jpn_vert
You can try without that
Also look at the settings for jpn in training/language_specific.sh
You may need to change the following also ..
# The following fonts will be rendered vertically in phase I.
VERTICAL_FONTS=( \
"TakaoExGothic" \ # for jpn
"TakaoExMincho" \ # for jpn
"AR PL UKai Patched" \ # for chi_tra
"AR PL UMing Patched Light" \ # for chi_tra
"Baekmuk Batang Patched" \ # for kor
