I referred this journey for some predecessors. They did not recommend to walk Tokaido by foot within few weeks. I absolutely agreed with their opinions. I know, ordinary people have never thought doing so. Landscapes does not change dramatically. Current point on Google Map remains. Strong pain on legs and sudden rain.
Yes, you can experience extraordinary things, such as only few people walk R1, only few young people in town on daytime on weekdays.
But, I strongly recommend dividing journey or walk 20km every day. Some people walked Tokaido every weekend, so they move week by week, It’s better for their health. Others walked 20km every day, which means they walked about 8 hours each days. 40km is too much.
I wrote down some tips based on my experience for someone who walk Tokaido in the future and for my future challenge.
Better to have
Mobile phones: for taking pictures, navigations. It’s better to bring spare batteries.
Sunscreens: walking whole days, so it’s important to protect your skin from sunshine.
Vantelin: To relief muscle pain and quick recovery.
Running shoes: thick soles are better, because walking whole day.
Trekking poles: useful not only for walking passes, but also for flat road. They support your walking.
Depend on situations
Household medicine: If you stay at business hotels, they would share you.
Jeans: I recommend trekking pants, because jeans are hot.
