What is a "wrap around jacket band"? I have seen this mentioned in some anime reporting. It sounds like an anime forum or a magazine, but strangely I can't find any information on it.

The news broke to fans on the wrap-around jacket band of the most recent tankobon manga volume released today in Japan. (source)
It is an obi, which is also known as

a strip of paper looped around a book or other product.

As Wikipedia continues to mention,

Many books in Japan are supplied with an obi, which is normally added outside any dust jacket. [...]
In English, the term belly-band is sometimes used instead.
