4/6【開通日走行】赤城の秘境道！大胡赤城線サンダーボルトラインが冬期閉鎖解除開通したから、バイクツーリングして赤城山秘境の露天風呂で日帰り温泉

On April 6, 2026, the Thunderbolt Line (Prefectural Road 16, Ogo-Akagi Line), the last road on Mt. Akagi that had been closed for the winter, reopened. This video documents a motorcycle tour descending from Lake Akagi-Onuma, showing the newly reopened road surface, and includes a day trip to a secluded hot spring inn (Takizawa Onsen Takizawa-kan), one of the Akagi Onsen hot springs, where the open-air bath by the river, with no roof, has the feel of a natural hot spring bath. #MtAkagi #AkagiOnsen #ThunderboltLine #OdekakePoco #GunmaPrefecture #TakizawaOnsen #TakizawaKan #OpenAirBath
