I didn't expect there to be a museum dedicated to hot springs. I learned that it can take around 50 years for a drop of rainwater to become hot spring water. I really learned something new.

Hiroshima Castle Sannomaru
A commercial complex that opened in 2025 to bring new activity to Hiroshima Castle. Located in the Sannomaru area overlooking the castle tower and moat, it features shops where visitors can experience Hiroshima's history and culture.
I originally just came to see Hiroshima Castle, but Sannomaru was also quite nice to explore. The space is beautifully designed, and the wooden buildings and landscaped courtyard have a distinctly Japanese feel. It's clean and stylish, and a nice place to take a short break when you're tired from walking.

Lake Shusenko
A dam lake that stretches along National Route 341 in Semboku City, Akita Prefecture. In the center of the lake, Shusenko Dam Park is maintained, offering a beautiful contrast between the cobalt-blue water surface and the surrounding trees. It’s also known for the limited-time scenic view called the “submerged forest,” which can only be seen from May to around mid-June.
The first time I saw Lake Shusenko's submerged forest, I was truly amazed. The lake was incredibly blue, and together with the fresh green leaves that had just sprouted, the whole scene looked magical. It was even more beautiful in person than in photos.

Sumida River Terrace
Sumida River Terrace is a waterfront promenade developed by the Tokyo Metropolitan Government along the levees of the Sumida River to improve earthquake resistance and create spaces where people can enjoy the waterfront. About 36 km of the approximately 47 km along both banks has been completed. Despite its central Tokyo location, it offers an open, relaxing setting for walking and jogging.
It's not as noisy here as the popular attractions, and walking along the Sumida River is very pleasant. The waterfront promenade is well designed and very close to the river. Walking slowly by yourself actually feels especially relaxing.
