Note

I think about the era and there is a problem in the following.

• The date in the lunar calendar Although it is September 8, 1968 the start of the Meiji era.
• Start date Taisho, Showa is the same day as the last day of the Meiji, Taisho, respectively.
  • 昭和ト改元
  • 大正十五年十二月ニ十五日以後ヲ改メテ昭和元年ト爲ス
  • 明治45年（1912）7月｜大正と改元：日本のあゆみ
