For every person with a night stay that exceed 7,000 yen, there will be an additional 100 yen charge as an occupancy tax.
ご質問ありがとうございます。
「1泊1人7000円以上で100円の[料金](https://eikaiwa.dmm.com/uknow/questions/34957/)が発生します」と言いたいなら英語で「For every person with a night stay that exceed 7,000 yen, there will be an additional 100 yen charge as an occupancy tax.」と言えます。
ご参考になれば幸いです。
