Japanese oolongs are limited in production and rarely leave the country, but they are growing in popularity and I expect they will become easier to find.
Why the new interest in oolong tea in Japan? The explosive growth in milk tea and boba is one part of the explanation; the other is that it has been historically desirable to import well-crafted Taiwanese oolongs. As Japanese teas become better known outside the country, producers are finding new markets and are able to experiment with less common processing styles.
