'How to add Japanese citations?

I know how to add Japanese text to my dissertation, but when I try to do it in a citation, it does not work. I get a "?" in the resulting .pdf and the citation is not added to the bibliography.

This is my main.text. I know it has a lot of packages, but I need them for other things. I am using natbib for bibliography since it works well for me and the {CJKutf8} package for Japanese text.

%Preámbulo

\documentclass[11pt]{report}
\usepackage[utf8]{inputenc}
\usepackage{multirow}
\usepackage[table,xcdraw]{xcolor}
\usepackage{adjustbox} 
\usepackage{caption} 
\usepackage{ragged2e}
\usepackage{floatrow}
\usepackage{graphicx}
\graphicspath{{../figs/}}
\usepackage{pdfcomment}
\usepackage{geometry}
\newgeometry{left=2.5cm,right=2.5cm,bottom=2.5cm}
\usepackage[english]{babel}
\usepackage{CJKutf8}
\pagestyle{headings}
\usepackage{blindtext}
\usepackage{csquotes}
\usepackage{titlesec}
\usepackage[T1]{fontenc}
\usepackage{imakeidx}
\makeindex[columns=3, title=Alphabetical Index]
\usepackage{array}
\usepackage[format=plain, labelfont={bf,it}, textfont=it]{caption}
\usepackage{fancyhdr}
\usepackage{subfiles}
\usepackage{hyperref}
   
\hypersetup{
    colorlinks=true,
    linkcolor=black,
    filecolor=black,      
    urlcolor=black,
    citecolor=olive,
    pdftitle={PhD Dissertation},
    pdfpagemode=FullScreen,
    }

\urlstyle{same}

\bibliographystyle{abbrvnat}
\usepackage[authoryear]{natbib}%/bibliography apa
\setcitestyle{authoryear,open={(},close={)}} %Citation-related commands

\setlength{\parindent}{0em}
\setlength{\parskip}{1em}
\renewcommand{\baselinestretch}{1.5}

\pagestyle{fancy}
\fancyhf{}
\fancyfoot[R]{\thepage}
\fancyhead[RO]{\slshape\nouppercase{\leftmark}}

\titleformat{\chapter}{\normalfont\Large}{\thechapter.}{20pt}{\Large\it}

\setcounter{tocdepth}{3}

%documento

\begin{document}

\subfile{Chapter}

\bibliography{bib}

\end{document}

In the chapter the citation would be:

\documentclass[../main.tex]{subfiles} 

\begin{document}

Hello citation \begin{CJK*}{UTF8}{min}\citep{岡崎_2005-1,goodman_assessment_1990}

\citep{岡崎_2005-1}\end{CJK*}

\end{document}

and this is the bib.bib file

@article{岡崎_2005-1,
    title = {歯冠サイズに基づく未成人骨の性判定―性差の集団間変異の検討と出土人骨への応用―},
    volume = {113},
    url = {http://jlc.jst.go.jp/DN/JALC/00272144846?from=Google},
    doi = {10.1537/asj.113.139},
    number = {2},
    urldate = {2016-01-31},
    journal = {Anthropological Science (Japanese Series)},
    author = {岡崎, 健治},
    year = {2005},
    pages = {139--159},
}

@article{goodman_assessment_1990,
    title = {Assessment of systemic physiological perturbations from dental enamel hypoplasias and associated histological structures},
    volume = {33},
    url = {http://onlinelibrary.wiley.com/doi/10.1002/ajpa.1330330506/abstract},
    doi = {10.1002/ajpa.1330330506},
    number = {S11},
    urldate = {2016-03-23},
    journal = {American Journal of Physical Anthropology},
    author = {Goodman, Alan H. and Rose, Jerome C.},
    year = {1990},
    pages = {59--110},
  }

I hope I have provided all the information necessary. I can cite and I can add Japanese text, but I do not know how to cite Japanese names. I would appreciate any advice.

Thank you.
