Your question can not be answered objectively.

Yes, there are some lenses specialized in architectonic photography to eliminate perspective distortions. But you are not working for an architectural magazine. Yes, there can be lenses more suitable for some users. But that needs to be defined by the user.

So, instead of giving you a lens opinion, a tip I can give you is:

Be a tourist in your own hometown for a day. Take your camera and capture everything you can in your hometown to show it to the world. And I mean all day.

If your hometown is really, and I mean, really small (or insecure) go to a nearby city.

Take some photos during the day, some during the afternoon, and some at night. That is the only way you will find the limitations of your current gear, and then, plan a new purchase. Probably night photography will be interesting in Japan because of all the neon lights and the safety of walking at late hours.

The only difference could be the height or dimension of the buildings. You probably have no skyscrapers in your town, but how you use your camera is what matters.

Also, carry your cellphone and take some photos with it.

What is important intitially is not the lens, it is What you want to see and capture with our camera.

Then and only then, you plan to get a new lens to facilitate your work.
