This has nothing to do with "Asian concepts".
Bengali is an Indo-Aryan language distantly related to English, but Japanese belongs to a completely different language family.
The only similarity between Bengali and Japanese are the syllabic writing systems.
Thank you for your well-written information @wentong-syhhae

Your country's recent history is so sad, but I admire your literature, especially Tagore's poetry. I wonder if there are many westerners who study Bengali. https://steemitstage.com/language/@wentong-syhhae/similarity-between-bengali-alphabet-and-japanese-kana
