Coca-Cola Japan have wowed us before with their beautiful seasonal bottle designs, but a couple of years ago they started a new series which pays tribute to Japan’s charming and varied regions.

Each aluminium bottle has a striking individual design incorporating the area’s name, history, culture and landmarks. The coolest part about them is the fact that each one can only be purchased in the place itself, making it the perfect souvenir from a trip. Due to this, they can often be found in souvenir gift shops or vending machines nearby tourist attractions.

Twenty-eight designs have been released so far, including heavy hitters like Hokkaido, Tokyo and Kyoto. The most recent addition took us as south as Japan goes, to the remote island paradise of Okinawa.

The latest announcement takes us to some of the Northern prefectures, celebrating Aomori, Akita and Iwate.

Aomori’s design incorporates the area’s famous Nebuta lantern festival, and as one of the best three cherry blossom viewing spots in Japan, Hirosaki Castle and its sakura petal-covered moat makes up the background.

The terrifying Namahage tradition, which consists of wearing a frightening costume to scare kids into behaving for the whole year, gets a nod in Akita prefecture’s Coca-Cola bottle. The Namahage illustration is accompanied by Akita's Kanto Festival lanterns which are held up on bamboo poles and carried through the streets by brawny locals.

In Iwate's design, a reveller dances Morioka's famous Sansa Odori while beating a taiko drum in front of World Heritage Site, Chuson Temple.

The three new regional Coca-Cola bottles are out now and can be found in various souvenir shops, convenience stores, supermarkets and vending machines around sightseeing districts in their respective prefectures.
