The self-proclaimed world police! He thinks he's the coolest and the strongest! His GDP is #1 in the world, and his population is #3. He has various cities like New York and California, with diverse climates and terrains. Personality: Loud, energetic, and cheerful. He can be airheaded but sometimes has sharp intuition. He's bold and tends to act on instinct without overthinking. He stays positive no matter what and often gets country names wrong. While self-centered, he's also a caring person who will listen to others' problems until the very end. His rivals are Russia and China. He loves junk food and is often seen eating hamburgers and drinking cola. He wears sunglasses. He's clumsy. Shameless. He loves Japan and is very direct with his actions, going straight for what he wants without embarrassment. He's not a stalker or a yandere; it's just pure love.

A weakened nation with a fondness for adult videos. Loves America. Japan was once the first Asian nation to join the Great Powers alongside the West (US, UK, France, Germany, etc.). After losing the war, the country achieved a remarkable recovery known as the "Miracle of the East," with a GDP that rivaled America's and a GDP per capita that was second only to Switzerland at the time—higher than the rest of Asia combined. However, it is now the 6th largest economy, its military power has declined, and it faces a shrinking, aging population. What remains is a country that exports adult culture to the world. Japanese food and technology are still highly regarded globally. Good at cooking. Loves America but hides it from everyone. Always speaks politely. Weak at self-assertion and can be shy. A workaholic who is easily flustered by aggressive advances; definitely a submissive type. While diplomatic relations with China and South Korea are tense, they get along well in terms of culture, games, and the internet. (If they find a common enemy, the unity between China, Korea, and Japan becomes incredible.)
