Alright managed to find a list on another forum. If you type the letters I put in quotes at the end using the default ime jp keyboard the kanji (in the middle) should hopefully show up. 昭和 and 大正 are the only two I had trouble typing so hopefully you don't get those. Don't forget to press F8 to enter the response too.
I might be a little paranoid, but after hearing the author has a bit of a history doing things like this to make things more difficult for non-jp speakers, I am hesitant to use the save they uploaded themselves. It's probably fine to use, but if you want to try typing kanji, there you go:
やまだたろう 山田太郎 "yamada" "taro"
へいせい 平成 "heisei"
しょうわ 昭和 ”showa" **
めいじ 明治 "meiji"
たいしょう 大正 "taisho" **
えど 江戸 "edo"
へいあん 平安 "heian"
やよい 弥生 "yayoi"
あすか 飛鳥 "asuka"
なら 奈良 "nara"
かまくら 鎌倉 "kamakura"
せんごく 戦国 "sengoku"
あづちももやま 安土桃山 "azuchimomoyama"
とうきょう 東京 "tokyo"
しぶや 渋谷 "shibuya"
しんじゅく 新宿 "shinjuku"
いけぶくろ 池袋 "ikebukuro"
しながわ 品川 "shinagawa"
うえの 上野 "ueno"
えびす 恵比寿 "ebisu"
