Booking tickets on Klook was very convenient. I bought a 1:30 PM boat ticket, and the meeting time was 12:00 PM. We registered first, then had free time to explore the exhibition hall and buy souvenirs. There was plenty of time, and we met at the pier across the way at 1:00 PM. The staff's instructions were very detailed. Unfortunately, the weather was bad, and it started raining when we arrived at Gunkanjima (Battleship Island). The staff thoughtfully provided us with raincoats. Everyone should bring an extra windproof and waterproof jacket, as it gets quite cold out at sea. If the weather is good, a hat and sunglasses are essential. The boat will circle Gunkanjima on the way, allowing everyone to take photos. The entire trip concluded, and we disembarked at the pier at 4:30 PM. Therefore, if you can arrive early to visit the exhibition hall and shop beforehand, you can leave directly after disembarking, without needing to go back to the exhibition hall. If you're driving, there are convenient parking lots near the pier and exhibition hall.
