これ、持ち帰りはできますか？ — Is it possible to take this to go? (Cultural · Dining, Polite to Staff, JLPT N5)

Gesture & etiquette

Ask quietly so as not to draw attention from other diners. If refused, accept gracefully with a nod — pushing back or expressing disappointment is considered rude in a restaurant setting.

Doggy bags are traditionally uncommon in Japan — many restaurants decline takeout for quality or hygiene reasons, and asking was once considered impolite. This is changing in cities, but be prepared for a polite refusal in traditional or high-end restaurants.
