How do I ask for different steak temps when ordering in Japan?

Question:

,Bleu, Rare, medium rare, well-done, extra well-done, broiled to a pile of ashes, etc.

Answer:

Just say,

Rare, レア
medium rare, ミディアム
well-done　ウェルダン

Others like ashes or something are not common. Maybe you can order it if you speak Japanese.
