This thread really useful...back to here again to plan for next year Jun'16 trip to Osaka/Kyoto/Nagoya for 11D10N...how's the weather likely for 1st 2 week of June?

Last visit was to Tokyo May'2013 back then with joyful memory trips....

Lastly correct me if I'm wrong that Malaysian passport holder does not need to apply for VISA for less than 90 days stay right?

Highly recommended to visit Osaka and Tokyo.

For me...Sapporo ,Hokkaido ..nothing interesting here..unless if you want see nature .Recommended rental the car and start traveling to Furano,Asahikawa , Hakkodate , Toya Lake , Shiretoko ,Otaru and Niseko.....recommended traveling  Summer (June to August ),Autumn ( Mid of October to Early November )  and Winter..(End of December to February )

i bought 1 and found out the leather crack (aged leather)
then i bring it back, they said duty free items no exchange knn 

Sapporo are biggest city  in Hokkaido . I been many times here..well compare to Tokyo or Osaka. Not much activities you can do here..recommended...Susukino / Sapporo Eki / Sapporo Tower / Odori Koin .

Shinjuku are more happening ..
