@Jach, thank you for very honest tips. "Be worse" — this is a shock for me! But I understand what you mean on HN. I will try to use my "broken English" more. (Actually, I think it might be more difficult for me... ^_^)

About Japanese nouns, that's very interesting. I didn't know words like "Tanren" (鍛錬) look like a "meme". For me, a local banker in Gunma, these are just daily words. But I see how they sound too "mysterious" or like a marketing trap here.

Your "Bin" (bottle) story is a very weird and funny analogy, even for a Japanese person like me. I will be careful not to make every word into a zen philosophy!

By the way, is this reply "worse" enough?

Next time you come to Japan, please come to my hometown, Gunma. I will teach you Japanese then ^_^. Thank you for helping me.
