The city of Toyota in Aichi Prefecture is home to some 18,000 foreigners, mainly Latin Americans of Japanese descent. We follow one of them: Keiko Uezu from Peru, who works as a caregiver assisting non-Japanese elderly and disabled people in their daily lives. Fluent in Japanese, Spanish and Portuguese, she's an indispensable source of support and reassurance for those struggling with the language barrier. We also visit a hard-working Polish salesclerk at an eyewear store in Fukuoka Prefecture.

Struggling with depopulation and a dwindling farming industry, Akitakata City in Hiroshima Prefecture has been encouraging foreigners to settle down in the area. Among them is Leonel David Maia from East Timor. Training under a veteran farmer, he started growing peanuts that now rank among the region's best-selling produce. We take a close look at Leo's efforts to reinvigorate local agriculture. We also meet an Italian craftsman eagerly promoting the use of traditional pizza brick ovens in Japan.

We revisit Aussie chef Benjamin Flatt and lacquerware artist Suzanne Ross from the UK in their efforts to preserve the culture of their adoptive Noto in the aftermath of the quake that hit a year ago.

We meet Austrian fashion designer Edwina Horl Ota who works to bring her late husband's Tokyo ramen shop back to its former glory, and Chinese Masuda Sei who cleans up bullet trains at Tokyo Station.
