Originally an "energy hall" to promote nuclear power generation, the building is castle-like, contrary to its name. Tomioka Town is in an area that was hit hard by the tsunami, but the area where this building is located did not reach it. The tour itself is free, but reservations are required. I decided to go the night before, so I couldn't make a reservation. (Opening hours only) I checked in at opening time and went inside for the first morning session. The tour time is 60 minutes (there are also 90-minute sessions). You can enter every 30 minutes. You cannot tour on your own. You are required to watch with a guide. You are not allowed to stay after the tour time is over, and you have to leave. This time, it was a 60-minute course, but it felt a bit rushed. The overall flow is "watch a video, then a staff member gives an explanation" for each exhibition space. The first prologue begins with "looking back and reflecting on the nuclear accident." First, there is an explanation about the nuclear power plant and the reason for the accident using a model. Next, we look back on the response over the 11 days since the earthquake. We also look back on the accident in the central control room. The video "Looking back on the accident in the central control room" was shown for the first time when I visited. Next, we see the efforts toward decommissioning and the measures to treat contaminated water. (Currently, contaminated water is being released into the ocean, but at the time it was before it was released.) Finally, the latest status of the Fukushima Daiichi Nuclear Power Plant is displayed on a huge three-sided LCD display called F-Cube. It is a place where you can feel close to the facility where decommissioning work is being done, and it seems that it could not be displayed anywhere else. The content is quite realistic, but surprisingly, photography was allowed. The content was a straightforward explanation of the nuclear accident and the reconstruction work from the perspective of the company. First of all, the fact that you cannot freely visit is a significant minus. There are many detailed exhibits, but you are not even given time to look at them. I think that even the 90-minute course is probably not enough time. It seems that they are deliberately making the restrictions strict in consideration of how to deal with people who visit with malicious intent. When I went there, there were only ordinary tourists.

This facility explains and exhibits the decommissioning status of Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Plant. It was originally an ordinary public relations center, but after the accident it started exhibiting decommissioning-related items. When I went, it was a 60-minute guided tour, so I wasn't able to see all the exhibits, but the detailed explanations gave me a good understanding of what happened at the time of the accident, what they are doing now, and what they will do in the future. There is also a thorough explanation of how the treated water is handled, and the guide will carefully explain any points you don't understand. I think it's a great place to visit at least once to learn about the details of the accident.
