1) Are soya beans halal? Apparently, there is alcohol used?
2) Is sushi halal? Apparently, alcohol is used to stick the rice together?

In the Name of Allah, the Most Gracious, the Most Merciful.

As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.

1) Soya beans are plants grown naturally. We are not aware of any alcohol used in the production of the actual beans. Thus, there is no harm in consuming soya beans. Nonetheless, it must be noted that it is impermissible to consume Soya Sauce made from wine/alcohol. [1]

2) Sushi is made in various different ways. However, generally, it is made from fish [2] and can contain Rice Vinegar. In principle, Rice Vinegar is permissible to consume. [3]

Accordingly, if the sushi consisting of fish and Rice Vinegar contains no other unlawful contents like alcohol, then it may be consumed. [1]

Finally, it must be noted that sushi is often served with Rice Wine, which consists of varieties such as: Sake (Japanese drinking wine), Huangjiu (Chinese rice wine) and mirin (Japanese cooking wine) etc; all of which are used as alcoholic beverages. Thus, the Rice Vinegar of a permissible nature (outlined above) must not be confused with the Rice Wine that would be deemed impermissible to consume.

Note: The guidelines outlined above with regards to Soya Sauce and Sushi are merely indicative principles. Nonetheless, it is difficult to issue a blanket ruling on such products with many varieties. Hence, we advise that one contacts the specific brand or supplier of such products and thereafter, one should refer to reliable scholars for guidance. 

And Allah Ta’āla Knows Best.
