According to google trends, both are being searched from japanese locations, though the one listed here appears most popular. The other which you are referring to is a form of kanji which uses chinese sysmbols. Though the symbols themselves are chinese in origin, they still get used in the japanese language. The best way to determine if these chinese symbols are being used in japan or just in china is to use google trends to determine search location and origins. So basically according to those tools, both are from Japan, but are just two different writing forms:
Kanji - Uses symbols derived from chinese
Katakana or Hiragani - Uses strokes and symbols that are phonetic
Both systems are used nowadays in japan, some terms are only spelled out in katakana or Hiragana (like brand names, exact words sounds or titles of countries, scientific names, foreign words etc..). Trends and exact search volume are the best indicators in determining which actually gets used and in what form. Some only exist in one form of writing while others might exist in all 3 forms, the tools for search volume and trends are the best way to determine which is actually the popular form(s). If there are native speakers here that could clarify this that would be ideal.
