LONDON — Japanese visitors to a picturesque corner of Britain are being asked to pay a small levy for the upkeep of the area — the first time a particular nationality has been targeted for donations by conservationists.

Japanese are being invited to make a discretionary payment of £5 (about ¥680) when they book their vacations in the Lake District, which lies about 400 km northwest of London and was home to the celebrated children's author Beatrix Potter.

The payment is designed to help the National Trust conserve the landscapes made famous in Potter's books.
