Chrysanthemum Bunker

The Chrysanthemum Bunker is a new bunker added in the v0.6.7 "Community Collage" update on November 29, 2018. It is currently the only place to locate the Imperial Seal skin and the one of two ways for the Katana, the other being in the fourth room in the Hatchet Bunker during the "If a bunker opens in a forest..." in replacement of the Fire Axe if it doesn't spawn.

Update log
The greenhouse was concepted by FJV. This glassy structure is home to several planters growing varieties of flora not native to the Island. Smash those planters and grab the loot! And for the diligent decoders among you, a mysterious bunker lies beneath the greenhouse.

Location
The Chrysanthemum Bunker is always found in a far corner of the Greenhouse. There is only one entrance which serves as the only exit.

Layout
There are two rooms in this bunker, and a vault at the end.

Room one
When entering the bunker, players enter a room which has a couch facing a TV, as well as some buttons on the walls. Behind the TV is an automatic door that unlocks when the first puzzle is solved.

There are some lockers on the side wall next to the entrance.

Room two
After the first puzzle is solved, the automatic doors open to a room where a series of planters are situated in the center. There is nothing but the planters and a recorder. The vault opens when the puzzle is answered correctly.

Vault
The last accessible area of the bunker is the vault. The vault contains some computer terminals and the Katana weapon.

Additional area
This is now available as of December 13, Desert Rain update.

Inside, there is a 15x scope(guaranteed) and 3 wheels. One is Desert wheel, which seems to be on(as the Desert Rain event is on), a Forest Wheel(which appears to be used, as there have been many woods mode), and a Winter wheel, which you can turn on and it will start snowing(confirms Winter mode).

Loot
The Chrysanthemum bunker contains the following exclusives:
 * Katana
 * Imperial Seal

Codes
Below are the two codes that unlock the second room and the vault.

Code for room one
Each button is labeled with symbols, one through four Chinese/Japanese characters. The code is just to press the buttons in numeric order.

Code for vault
The second room contains twelve interactive planters, which unlock the vault when used correctly.

Trivia

 * The back room of the vault features 3 valves that can change the island's looks, being desert, woodland, and winter with the frozen desert's update
 * This bunker has a lot of Japanese-related items. (Imperial Seal, Katana, and other symbols.)
 * The last door behind the glass had cracks in it on the first day since the update.
 * The cracks are gone now.


 * The first four numbers in Japanese and in Chinese are the same (一, 二, 三, 四)
 * In the second room with the flower code. The Eye Bunker symbol can be seen in the middle of the flowers.
 * Be careful when you try to enter this, as there's rare clothing and the Katana and it quickly transforms to a war zone.
