I have tried Chatgpt to decypher this poem and the result is really amazing:
I clearly identified the Japanese characters engraved on the metal object. Here is a transcription and explanation:
Transcription (romanji)
Hōrai no
yama no hotori no
sumiregusa
yoso no hanayori
utsukushikeri
Explanation in English
It's a waka (a classic Japanese poem of 31 syllables in 5-7-5-7-7).
• Hōrai (蓬莱): a legendary mountain in Chinese and Japanese mythology, associated with immortality and paradise.
• yama no hotori (山のほとり): at the foot of the mountain.
• sumiregusa (すみれ草): violets (flowers).
• yoso no hana yori (よその花より): more than other flowers.
• utsukushikeri (美しけり): they are beautiful.
👉 The overall meaning of the poem:
"The violets that grow at the foot of Mount Hōrai are more beautiful than all other flowers."
This type of poem combines nature and spiritual symbolism (here, the mythical Mount Hōrai → paradise, and the violet → simplicity and beauty).
