I’m traveling to Japan for 30 days. Should I get travel insurance?

Hey everyone, I’m heading to Japan for a full month soon, and I’m on the fence about getting travel insurance. It’s going to cost me around $100, and I’m wondering if it’s really necessary for a trip where I mostly plan on doing regular touristy stuff. Have you ever traveled to Japan for a similar length of time? Did you get insurance, and did it end up being useful? I’d love to hear your experiences and whether you think spending that $100 is a good idea or if I should just save it for enjoying the trip.
