There are two versions of this clover omamori, the one above for happiness and another for luck in romance (visible in the background). Both versions contain an actual four-leafed clover!
This is a popular charm for several reasons, one reason is because it makes an appearance in a well-known manga. Boku no Hatsukoi wo Kimi ni Sasagu or “I Give My First Love to You” is a manga by Kotomi Aoki that won the Shogakukan Manga Award for best shōjo manga for the year 2007. In the temple shop you can see Kotomi Aoki’s autograph which given as a gift to the temple.
The two main characters in the manga visit Ninna-ji during a school trip and exchange clover charms purchased at the temple. Ninna-ji and the charms appear several times in the series. We have some volumes in which Ninna-ji is featured at the temple shop, while they aren’t for sale we would be happy to show them to you! Fans of the manga series, many of them visiting on their own real-life school trips, often take home a clover charm as a souvenir of their visit to the temple.
A film version of the series was also released in fall of 2009, but from what I can tell from the synopses online, it doesn’t appear that Ninna-ji makes it into the movie adaption. If any one has seen it and can confirm or deny this, let me know!
