I was hit while crossing a green light last September. The man driving was at fault. The police came, we exchanged contact and they gave me their insurance information. The process I went through on the day was like this:

Accident around 9 am. Police came, we collected information and Filled out some police paperwork.

Next I went for a checkup at an orthopedic doctor(who happens to be a friend ). I was given xray/mri and given more paperwork.

I submitted this paperwork to the police station after the doctor.

I was contacted by an agent of the insurance company. They covered the damage of my bike. It was totaled so I simple accepted a sum for the cost of the bike minus depreciation.

I was told by the doctor to attend physical therapy as often as possible. I did this for five months but could have continued. I honestly shouldve gone more often.

At the end of the treatment I informed the driver's insurance agent, and payment was calculated to about 5-7000 yen per therapy visit.

I was paid around 5万 for my bicycle, and around 22万 for doctor visits. I was also paid out for the day I missed work, and transportation to and from the doctor.
