9/19-9/22, Sanyo area and Naoshima.
Some place in Naoshima could not find signal, others were ok totally.
Everything was good, like the service,and the conversations between staff, etc.
Only 1 thing made me confused.
The convenience store in Shin-Osaka Eki did not accept the package marked " precision machinery 精密機械".
I found the other store which could send it back for a while.
But I thought it might be the rule of Takkyubin, not the miss of RTM.
So, I'll still choose RTM in case of traveling in JP.
Thank them very much.
