What Japanese writing is written on the torii gate?

The Japanese writing on a torii gate, if there is any, is usually the name of the shrine it marks the entrance to. It's written in kanji, the Chinese characters used in Japanese writing.

However, it's important to note:

* Not all torii gates have inscriptions. Some are plain and simple.

* The specific kanji used will vary depending on the shrine's name.

* The placement of the inscription can also vary. It might be on the front beams of the gate, on the pillars, or on a separate plaque nearby.

If you're looking at a specific torii gate, you can try to identify the kanji and then look up their meaning to understand the shrine's name. You can also find more information about the shrine online or by visiting the shrine's website.
