A Japanese friend said that Kurama-dera temple in Kyoto, Japan is popular with those praying for love, both with people who are single and those who are in an existing relationship.
However, I can't find a mention of that on either the English or Japanese-language editions of Wikipedia, or Japanese Wikipedia's article on Yuki-jinja shrine, or by googling about Kurama-dera and love. However, the English edition of Wikipedia mentions that the temple isn't well-known by non-Japanese, so that may explain the lack of google hits confirming this.
Is Kuruma-dera popular with those praying for love?
