Which Japanese term names restaurants specializing in tempura?

Restaurants specializing in tempura are called tenpura-ya.

The term combines tenpura, the Japanese word for tempura, with ya, a suffix meaning a shop or establishment. In English, tenpura-ya can therefore be understood as a “tempura shop” or “tempura restaurant.” The spelling tenpura reflects Japanese pronunciation, although English commonly writes the dish as tempura.

A tenpura-ya may serve tempura as a formal meal, a set menu, or part of a broader menu. Specialist restaurants often emphasize seasonal ingredients and fry pieces individually, serving them as soon as they are cooked. Typical accompaniments include tentsuyu dipping sauce, grated daikon, or salt.

The other choices describe different kinds of Japanese establishments or businesses. Kissaten is a traditional coffee shop, izakaya is a casual pub-style restaurant, and sushi-ya is a sushi restaurant. A restaurant can offer several of these foods, but only tenpura-ya specifically identifies a tempura specialist.
