すみません、これ中がちょっと赤いんですけど、このまま食べても大丈夫な焼き加減ですか？
すみません、これなかがちょっとあかいんですけど、このままたべてもだいじょうぶなやきかげんですか？
Excuse me, the inside of this is a bit pink. Is it cooked enough to eat safely like this?

はい、新鮮な鶏肉を絶妙な火加減で焼いているので大丈夫ですが、よく焼きに焼き直すこともできますよ。
はい、しんせんなとりにくをぜつみょうなひかげんでやいているのでだいじょうぶですが、よくやきにやきなおすこともできますよ。
Yes, we use extremely fresh chicken cooked to the perfect doneness, so it is safe. But we can grill it longer for you if you prefer.
Gesture & etiquette
Point politely to the inside of the skewed meat using your chopsticks, or show the piece to the staff.
Do not rudely complain or accuse them of serving raw food. In Japan, high-quality chicken (like Yakitori) is sometimes served medium-rare intentionally. Politely ask to cook it more if you feel uncomfortable.
