When we will enjoy cycle.travel planning route through Asia?

Hello the creator of this absolutely great tool for long distance real usage route planning.

I have already used so many of planners (b.router, Maps, komoot, Garmin) but this one is, for me, the best one ever.

Let's dream a bit: in a year I begin a Bordeaux (France)-Sapporo (Japan) cycling trip, alone.

I wish I can plan my itineraries with cycle.travel all along.

However, if Asian coverage is not planned to exist, which route planner would you recommend then?
