Is Biwaichi (cycling around Lake Biwa) possible in one day?

We do not recommend it. To complete the ride within our business hours (normally 9 a.m. to 5 p.m.), you would need to continue cycling at 30 km/h, even after taking traffic lights and breaks into account.
This would be an extremely challenging itinerary in practice.

We recommend planning for at least two days and one night.
With a relaxed schedule of three days and two nights or more, you can also take your time enjoying sightseeing in various locations.
