I haven't heard this saying before, and I would think it would be worth a bit more without the "to" in it. But. . .
It's worth what you make out of it as I always say in this forum and I'm sure you know.
I also think tours are huge there wether its just group tours, baseball teams etc. . .
about 290,000 for "tour japan".
I'd say mid xx undeveloped. . . it'd be interesting to see what the type in traffic is.
Good Luck! !
