Need help about housing rental issue

I am currently renting a residence in Ikebukuro. However, due to an accident that occurred while I was traveling in Taiwan, I was unable to return to Japan to handle matters related to the property when my lease expired 10 days ago.

My landlord is now requesting to dispose of my belongings in the apartment. Over the past two days, I have asked whether they could delay this process, but my request has been refused.

I would like to ask what I should do next, or if there is any organization or authority I can seek assistance from.
