Since it's been put on hiatus on February 2014, no new chapter of Arata Kangatari has been published yet. On early May Watase Yuu the mangaka announced that the return date has been decided. Arata Kangatari's new chapter will be out on July 8 in the 32nd issue of Weekly Shounen Sunday. The mythical fantasy series will resume its weekly release schedule.
MYTHICAL FANTASY: Arata Kangatari will resume it's weekly serialization starting July 8.
Watase had hoped to publish two new chapters simultaneously but it's impossible due to page circumstances. Last year Watase said that she wanted to resume the series in October but it was delayed until mid 2015.
Hopefully there won't be hiatus anymore.
