Horifuda are essentially the Japanese versions of keychains, so you can understand why they’re great souvenirs. These wooden charms feature engravings of just about anything you can imagine. Many shops have a large selection of pre-made horifuda with English and Japanese names as well as sayings and wishes.
However, what you should really do is get one custom made. This can cost a little more, but not much, and you can get almost anything you want translated into Japanese. Names make great gifts, or if you want something for yourself, you can go with Shinto prayers or wishes for family members and friends. Couples can get both their names engraved as a perfect memory.
