Residents in a coastal region of Japan have placed special alert signs to caution individuals about the seasonal crab migration. The move follows instances where the migrating crustaceans disrupted daily activities, with an increase in recent years. These signs, mobilized without local government intervention, are the community's effort towards cohabiting harmoniously with their crab companions.

The Japanese have a strong admiration for the harmony of nature and urban landscapes. Hence, when occurrences such as the crab migrations disrupt human activities, solutions like signage that ensure co-existence without causing harm to the fauna are highly favored. Moreover, local community involvement in such matters conveys a strong sense of societal responsibility – a defining characteristic in Japanese society.

In the US or EU, wildlife-related issues are typically handled by local or national wildlife agencies or private wildlife charities. Community-based solutions such as this may be less common as a lot of emphasis is given to professional, official approach. However, community participation in conservation efforts is steadily gaining traction in these regions as well.
