It is no problem for a woman to eat alone in a Yakitori restaurant. There are often bar seats in Yakitori restaurants so you can choose to sit there, too. Recently, there are some restaurants dedicated for single visitors, such as Yakiniku (Japanese BBQ) restaurants for single visitors. There are charcoal grills put on each table.
