I think you've mistook Kanji characters(Japanese) as Chinese characters, some chars are the same even in writing order, even though not shared in the same char codespace.
In this instance, "稱" and "號" used on some of printed labels in place of "称" and "号" are outside of current Japanese common use(though "號" wasn't uncommon until very late in 20th century) and I can tell that the system used to print those labels must have been configured for Traditional Chinese(HK/TW). As for the handwriting, it just looks Chinese to me.
