Tokyo's Philatelic Museum published details of its Christmas exhibition on 11 October. The exhibition will run from 5 to 25 December 2026, with Christmas landscapes as its theme and five sections introducing stamps from around the world.

The programme includes three illustrated postmarks designed by Japan Post stamp designer Yusuke Kusuda. A temporary Toshima post-office counter will operate on 12, 20 and 25 December, from 10:30 a.m. to 5 p.m., in the museum's third-floor Space 1. A special posting box will remain available during the exhibition.

A Kusuda-designed postcard will go on sale at the first-floor souvenir counter on 24 November, priced at 120 yen including tax. A special talk by the designer is provisionally planned for 12 December.

The exhibition occupies third-floor Spaces 1 and 2. Admission costs 100 yen for adults and 50 yen for elementary and junior-high pupils; visitors presenting disability identification are admitted free. The museum closes on Mondays. Admission is free on 23 December, while use of only the postal counter or special posting box is free throughout the stated arrangements.
