If you are in Japan and looking to ask for vegan food, you can use the following phrases:
私はビーガンです(Watashi wa biigan desu) - This phrase means 'I am vegan' in Japanese.
私はベジタリアンです (Watashi wa Bejitarian desu) - This phrase means 'I am a vegetarian'.
私は肉や魚を食べません (Watashi wa niku ya sakana o tabemasen) - This means 'I do not eat meat or fish' and is another way to convey that you are looking for vegetarian food.
肉なし、魚なし、卵なし、乳製品なしでお願いします (niku nashi, sakana nashi, tamago nashi nyuuseihin nashi de onegaishimasu) - This phrase means 'No meat, no eggs, no fish, no dairy, please' and is a helpful way to specify your dietary restrictions in Japanese.
Some Japanese restaurants may not be familiar with veganism and they might not always be able to fulfill your wishes, so it's important to be patient and polite when asking for vegan options. Check out our VegeVege restaurant guide, if you want to make sure that your food is 100 % vegan
