OVERWORLD

The Minecraft Overworld is meant to represent the real world and its environment types. Environments Japan doesn't have lol. And since the whole point of this project is to both expand and reduce Minecraft into Japan, that means no deserts, savannas, red-rock canyons, icebergs, or rich jungles (They have sub-tropical forests at best).

Japan's natural landscape is mostly dominated by temperate forests and mountainous regions. This will make the diversity of biomes and climates smaller but better fit the narrative for this project, which is to trick you into thinking you're in Japan. And I can't pull that off when you spawn right between Canyonlands National Park, Utah, the Amazon Rainforest, and the Arabian Desert.

However I'm not just deleting biomes and calling it a day (Except for the Frozen Ocean, the icebergs are hardcoded in). I have overhauled these biomes into something completely new; for example, the Badlands has been reworked into an Autumnal Forest. The orange, red-rock, and sand have been substituted for regular stone and grass, but have transformed into an autumnal temperate forest with rich warm colors. I've also divided the biomes by seasonal characteristics, allowing the transition between biomes to feel more natural and less jarring.

Yomi

"When the creator goddess Izanami gave birth to Kagutsuchi, the kami of fire. Her husband, Izanagi, fueled by grief, marched down to retrieve her in Yomi, the land of the dead. The place where all who die make home."

Yomi, also known as the Land of the Dead, is the replacement for the Nether dimension. While being virtually identical to the Vanilla Nether, the flaming hot visuals have been replaced with a cold blueish-green to personify the world of darkness much more effectively. This realm is home to many yokai, such as the Shikome, Gaki, Goryo, Maikubi, Keneō, Okubi, Yurei, Datsue-ba, Wa nyūdō, and Katawaguruma. Homes can be found along the Sanzu River, containing lost souls known as Shiryō, who will trade and sell valuable Yomi artifacts.

NOTE FOR SHADER USERS: You may have to configure your shaders if you want to gain this misty blue color palette.

Ryugu-jo

"Ryūgū is a fantastical palace that appears in many legends and folktales. It is the primary residence of the dragon god of the sea and his daughter Otohime, and is home to the ocean’s royal court. The palace is populated by aquatic creatures who wear human clothing and have a society which mirrors that of the human world." -Yokai.com

Ryūgū-jō is the alternate of the End dimension of this data and resource pack. Replacing the Ender Dragon with the great Sea Dragon known as Ryūjin. One of the more notable changes is that the previous void of the End has been flooded with a vast ocean filled with coral and other ocean life.

NOTE FOR SHADER USERS: I don't recommend shaders for this dimension. A lot of shader packs cater to the vanilla end and often block out the cool skybox.

When you get into a world, make a wooden pickaxe, mine three stones for the stone pickaxe. you're going to be really disappointed to see that nothing with come up in the craft output. That's because I've completely reworked the progression system with stone and iron tools. The vanilla 'stone' tools are now the new iron tools; the item ID will say stone_pickaxe, but it's named Iron Pickaxe. And the vanilla iron_pickaxe is now the Tamahagane Pickaxe. So the new progression order is Wood > Iron > Tamahagane > So on.

!Iron

Upgrading to Tamahagane will be similar to upgrading Diamond tools to Netherite, in which you'll need a smithing template and an ingot at a smithing table to upgrade your iron tool to Tamahagane. The smithing template is very easy to craft with iron ore and cobblestone. To make a tamahagane ingot, you must gather iron sand from riverbeds with an Iron Shovel and smelt it into Raw Tamahagane. Which can be crafted into the ingot using regular Iron Ingots.

!IronSand

I can see this being very controversial, so I made numerous compensations to sweeten the deal:

• You can mine Iron Ore with a Wooden Pickaxe now.
• You get more Raw Iron from Iron Ore
• Tamahagane Tools (vanilla iron tools) are much more durable.

I just felt like the progression system was incredibly flawed, and the use of Wooden tools, save for the pickaxe (for a brief moment), was worthless.

As I said before, I removed sheep from all biomes due to my obsession with making this as accurate as possible. However, sheep are essential for wool and your first bed to sleep through the night, so I made some compensations.

• String (crafted into wool) can now be obtained through agriculture by growing Ramie Fibre.
  • Ramie Seeds are obtained from ferns.
• I understand people want to get a bed ASAP on the first night and not wait for a stupid crop to grow, so I made the Grass Bed, which can be crafted from Reeds (Hay Bales), which can be crafted from numerous foliage.
• As for Mutton, I replaced the item textures and name with Squid Meat, which can drop from yours truly.
