Unfortunately, there's no direct way of linking to the patent application (sad!) however, this is the easiest process to view a japan patent or application.

Go to the Japan Patent Office search page.

If it's a patent application (they are usually in the format of Year-Number ie: 2017-011300) then type the patent application number into the second field down from the top where it says publication of patent application.

Click on search.

Then click on the patent application number link, and there's the patent application!
