The Wild Trip finally begins! Why has Yugo Kochi ended up embarking on this grueling journey as the "Wild Tripper"? And why did Shigeyuki Totsugi become the "Wild Planner," responsible for coming up with the missions? The answers are revealed during the pair's rare first meeting and conversation. Joining Kochi on this trip are Rinne Sugeta and Kuto Chiino. After being dropped off at an undisclosed location somewhere in Hokkaido, the three are informed on the spot of the grueling mission devised by Totsugi. They are also given a travel budget, the amount of which is determined by a certain condition. With no idea where they are, the trio begins asking locals for information and decides to try hitchhiking as a way to get moving. But one unexpected twist after another unfolds, forcing Kochi and the others to realize just how demanding this journey really is.

Yugo Kochi, Rinne Sugeta, and Kuto Chiino are on their way to Rausu Fishing Port to meet a fisherman who knows Shigeyuki Totsugi. However, after hitchhiking, they unexpectedly end up somewhere far from Rausu instead. With no one around to ask for help, they have no choice but to spend part of their limited budget to purchase the right to ride in the production van for one hour. As night falls and the temperature continues to drop, the three finally manage to reach Totsugi's acquaintance, where another miraculous encounter is waiting for them. Experiencing the warmth and kindness of the local people, Kochi and the Junior members continue working toward clearing their missions. But their biggest challenge is still ahead: finding a place to stay for the night. With only a limited budget and the bare minimum of outdoor gear, Kochi and the others are forced to make the ultimate choice. Will they be able to overcome this hardship through the true grit of the Wild Trippers?

After successfully completing Mission Bingo in Nemuro, Yugo Kochi, Rinne Sugeta, and Kuto Chiino decide to remain in Nemuro for as long as time allows in hopes of achieving a double bingo by completing the remaining missions. Their first stop is a certain location where they hope to warm up after spending the night in a freezing cold tent. But will they finally achieve the long-awaited double bingo? The Wild Trip then moves into the Kushiro area. Joining the journey are Waku Motoki and Tatsuru Matsuo. However, the starting point that greets them is nothing short of "a scene of despair." On top of that, the mission devised by Shigeyuki Totsugi is designed to give them an experience completely different from what they faced in Nemuro. Although bewildered as they travel through snow-covered Kushiro, the three gradually make their way forward with the help and kindness of the local people.

Yugo Kochi, together with Waku Motoki and Tatsuru Matsuo, obtains freshly squeezed milk and heads to a local supermarket to buy supplies so they can make their own cheese. After purchasing the bare essentials for food and camping, they also stumble upon an unexpected "treasure." However, that discovery sparks a disagreement among the three, leading to the first-ever falling out between teammates in Wild Tripper!!? Later, Kochi tries hitchhiking to reach a hot spring where he has always wanted to go, one known for its view of swans. But with sunset fast approaching, he decides to use the "Golden Whistle" that Shigeyuki Totsugi gave him during the previous leg of the journey. The whistle's effect ends up dramatically changing the course of the rest of their trip through Hokkaido.

After finally enjoying the long-awaited "hot spring with a view of swans," Yugo Kochi, Waku Motoki, and Tatsuru Matsuo continue their journey. Waku remembers spotting a campground while they were traveling earlier, so the three ask the driver who picked them up while hitchhiking to take them there. But will they be able to secure a campsite without a reservation? Having gone the entire morning without eating, the trio reaches their limit from hunger. However, with very little money left, they are forced to make an ultimate choice: spend what they have on heating equipment or eat a proper meal at a restaurant right in front of them. Will they be able to enjoy a comfortable night camping? Then, after overcoming one challenge after another and welcoming a new morning, Waku and Tatsuru surprise Kochi with an unexpected proposal before they begin working on their cheese-making mission. How will Kochi react to the two's surprise?

Fresh off Yugo Kochi's dome tour stop in Sapporo with SixTONES, he's whisked away for a location shoot in the Tokachi region! Supporting a slightly reluctant Kochi on this journey are Rinne Sugeta and Takeyuki Mayumi. For the first time in the show's history, this is a day trip, meaning the trio must complete a bingo within a limited amount of time. As usual, they're dropped off in the middle of nowhere and immediately begin hitchhiking. This time, however, Kochi shows a more dependable side after learning hitchhiking techniques from Kono during the previous trip. Meanwhile, although his juniors, Rinne and Takeyuki, enthusiastically throw themselves into the challenge, a simple oversight causes them to make a series of mistakes, earning them a scolding from Kochi. This time, the trio also has access to buses and trains in addition to hitchhiking. With time running short, they'll need to make full use of both their wits and stamina as they race to complete their bingo card.

Thanks to the bingo bonus prepared by Shigeyuki Totsugi, Yugo Kochi, Rinne Sugeta, and Takeyuki Mayumi enjoy an incredible venison barbecue. However, because this is a day trip, they have only about two hours remaining at this point. With so little time left, completing the bingo looks extremely difficult, so the three decide to split up and tackle different missions in hopes of clearing them. Faced with a level of pressure and urgency they've never experienced before, the possibility of the show's first-ever failed bingo begins to weigh on their minds. If they fail to complete the bingo, the next area won't be unlocked, and the journey will have to restart from the Tokachi region. As a result, the next travelers, Fuga Onishi and Masato Takemura, can only watch anxiously to see what happens. Meanwhile, back in the studio, a discussion about "the person they'd most like to meet right now" reveals an unexpected side of Totsugi.

The Kamikawa area gets off to the best possible start as the team clears a mission in record time. Their next destination is the "Blue Pond and White Waterfall," but before the next bus arrives, they decide to explore the surrounding area in hopes of helping a local resident with a problem. Then, someone unexpectedly approaches them, and that chance encounter sets off a whirlwind of surprising developments. After such a smooth journey in the previous episode, everything seems to be going perfectly once again. But while traveling by bus, Yugo Kochi suddenly makes a completely unexpected decision. Traveling alongside him, Fuga Onishi and Masato Takemura are left bewildered and unable to stop him, and the bus ends up taking them somewhere they never anticipated.

After a string of miraculous events, Yugo Kochi, Fuga Onishi, and Masato Takemura complete the bingo on the very first day. But determined to become the first team in the show's history to achieve four bingos, the three split up to tackle separate missions. Fuga heads off in search of the mysterious "Earth Sauna," despite having little idea what it actually is. The destination turns out to be a snow-covered mountain, where he takes on a mission truly worthy of the name Wild Tripper. Meanwhile, Kochi and Takemura travel to Furano in search of the "center of Hokkaido." Having never successfully hitchhiked on his own before, Takemura takes on the challenge under Kochi's guidance. However, an unexpected turn of events pushes him to the brink of an emotional breakdown.

For the final area, Sorachi and Ishikari, Yugo Kochi and Shigeyuki Totsugi take on a Mission Bingo created by the Junior members. After removing their blindfolds and discovering that their starting point is in the Sorachi area, the two immediately set off to complete their first mission: "Fly in the sky over Sorachi." Eager to get started, Totsugi enthusiastically tries hitchhiking, only to experience firsthand just how demanding this journey really is. The pair then head toward the finish line in Sapporo, where they take on an unprecedented mission: "Appear in a live TV broadcast." With limited time, money, and no means of communication, how will the two bring their journey to a close in the bustling city of Sapporo?
