Release: Pre-WWII
Manufacturer: Nintendo Playing Card Co., Ltd.
This deck features a traditional form of kanji characters (‘kyūjitai’) used before 1947. (櫻 instead of 桜). However the 任天堂 name form is written left to right (‘yokogaki‘ – 横書き) which was common after WWII. Therefore this deck is likely dated to almost immediately after WWII.
Compare this to a similar deck of the same Hanafuda brand that dates from before the war.
