Hello guys, after 2 amazing Japan trips I had previously, I plan to visit Japan again!! I have visited Toyama, Kurobe, Matsumoto, Osaka, Kyoto, Tateyama, Nagoya, Tokyo these places. I need some of experiences from you guys.
I am currently looking at some of the amazing view attraction like Kamikochi ( my wife liked it sooooo much ) or something like Alpine route that kind of Splendid scenery.
I'm thinking of few places, but do suggest me if you experienced nice scenery which is a really must go.
1) Tokushima prefecture - Kochi, Kagawa, Ehime.
2) Fukuoka prefecture - Kitakyushu
3) Kumamoto & Miyazaki prefecture - Including Kagoshima
4) Ishigaki island
5) Okinawa.
Not plan to visit Hokkaido/ Aomori prefecture as I believe I will visit Japan during non winter season. ( most likely Autumn or Cherry Blossom season ).

If you been to Kamikochi, then there are no more hiking route in Japan can beat it already. Based on my experience, only China Yunnan can overtake it (amazing view attraction + Splendid scenery). After been so many country in world, so far still can't find a hiking route that can beat Yunnan.
Based on your list, I will go Shikoku. It more reserve, alot nature path.
