To get the keyword traffic estimation with long tail keywords

[OST企画開発]

Hi, I want to get keywords' traffic estimates such as Average CPC, Average Position, Click Through Rate and so on for each keywords. 

But the problem is I can't retrieve the estimated stats like above in certain words with the long tail keywords. (Simple words are available to retrieve the traffic estimates.) How can I get all estimated stats of long tail keywords?

Does this problem occur because the keyword is too minor to retrieve traffic estimation?

I set up correct  xsi_type Language, xsi_type Location and all other values.(My region is Japan and try to search complex words in Japanese.)

 I followed demonstration on the official site of AdWordsAPI on the link below and use the code on it .

https://developers.google.com/adwords/api/docs/guides/traffic-estimator-service

I attached the code and the result for reference. 

I hope I could improve this situation.

Hi,

Thank you for reaching out to us. Could you clarify if you encounter any error messages when you're retrieving these keyword traffic estimates? If so, could you provide us with the request and response logs for where this result occurs? Are the keywords you've provided the only ones that cannot pull estimates from or are there other keywords you're querying as well? Could you also provide us with your account number that you're encountering these issues with?
