The text and the pictures do not agree on which side of the coin is the obverse and which side of the coin is the reverse. Someone who actually knows which is which should fix this. --Suttkus (talk)07:22, 27 February 2013 (UTC)[reply]

Done, after looking through a bunch of sources. Thanks for bringing this up.Opencooper (talk)05:45, 29 January 2019 (UTC)[reply]

I can not go intoWP:CRYSTAL here, but there is the possibility of the mintage being split between emperors as was done in 1989. -Knowledgekid87 (talk)13:36, 1 April 2019 (UTC)[reply]

Hi Knowledgekid87

You reverted one of my several edits and suggested that we discuss it.

The changes in that edit were as follows:

• Changed "Meiji" to "Emperor Meiji". He would not normally be referred to as simply Meiji. His personal name was Mutsuhito and after his death he is referred to by the era name, i.e. Meiji-Tenno or, in English, Emperor Meiji or Meiji Emperor.

• Changed "Ex." to "e.g.". The normal abbreviation for "for example" is "e.g."

• Changed column headings. The first two columns present the same information, i.e. the regnal year. The first column is in English and the 2nd column is the same number in kanji. The 2nd column is not the "Japanese year" or "Japanese date" because, as repeatedly stated in the article, that would also have to include the era name and also the kanji 年 meaning "year".---Ehrenkater (talk)10:45, 16 April 2020 (UTC)[reply]

The only major thing I changed was the columns as that is the setup used in every yen, and sen article we have. Your other edits I restored as they were minor and helpful. Japanese coins are read as follows: 平成 → 九 → 年, in this case that would translate as "Year 9 of Heisei" put into English that would be 1997. Japanese coins use the emperor's year of reign as a date. -Knowledgekid87 (talk)18:04, 16 April 2020 (UTC)[reply]

Thickness of 1 yen coin is given 1.5mm with 1gram weight. One of the information is not right here, 1 yen coin may have different thickness or weight.37.111.157.107 (talk)07:51, 8 December 2022 (UTC)[reply]

The 1 gram weight is definitely correct per the Japan Mint's official website.[1] I have gone ahead and removed the thickness as un-sourced. -Knowledgekid87 (talk)23:22, 8 December 2022 (UTC)[reply]

I added a change with respect to the naming conventions of Emperor Emeritus Akihito. The article referred to "No one yen coins were released for circulation for the remainder of Heisei's reign." and putting Heisei in parenthesis adjacent to the former Emperor's name. This implied that the renaming associated with the end of reign of a Japanese Emperor had already happened. However, The naming of a former Japanese Emperor for the era they presided over is a posthumous tradition and not applicable, because as of the time of the edit, the Emperor Emeritus is still alive.FA Jon (talk)18:10, 24 April 2024 (UTC)[reply]
