In Inazuma Eleven 3 there are lots of areas (most in Japan) you don't unlock during the story. To have access to these places you need to find maps or defeat some "old" teams. Every area has its own gacha machine, shops and chests. And last but not least, you need players from these areas to complete the connection map. Note that Spark/Bomber and Ogre are different, in this sense, so I made two different sections. Here's the list of possible places to unlock:

Inazuma Eleven 3 Spark/Bomber

Osaka: the map is inside a chest to the right of Toramaru's restaurant.

Naniwa Land: buy the map at the G-Mart in Osaka.

Umbrella: defeat Occult at Naniwa Land (screenshot).

Tokyo Station: defeat Mikage Sennou (Brainwashing) at the park in front of Endou's house (screenshot).

Hokkaido: defeat Senbayama (Farm) inside the Ooedo Airport (screenshot).

Nara: the map is inside a chest at the beach of the Central Park, Liocott Islands.

Royal Academy: defeat Nose (Wild) at the park in Nara (screenshot).

Okinawa: the map is inside a chest to the left of the Tower.

Kyoto: defeat Oumihara (Mary Times) at their pitch in Okinawa (screenshot).

Fukuoka: buy the map at the G-Mart of the american area.

Ehime: defeat Yokato (Fauxshore) at their pitch in Fukuoka (screenshot).

Mt Magnido: complete the game at least one time (defeat Little Gigant), then go to Central Park. There's an old man on the right, talk to him. Then go to the Sea Turtle island: go up, then left, then go down until the dead end. Examine the blue light (screenshot) to unlock the new area.

Mt Magnido: complete the game at least one time (defeat Little Gigant), then go to Central Park. There's an old man on the right, talk to him. Then go to the Sea Turtle island: go up, then left, then go down until the dead end. Examine the blue light (screenshot) to unlock the new area.

Future: complete the game at least one time (defeat Little Gigant), then go to Central Park. Talk to the kid on the right to get the phone that takes you in the future. Use the phone again if you want to go back to the present.
