Railways and other businesses across Japan are celebrating the Emperor's enthronement ceremony with special offers.
The operator of the 333-meter-tall Tokyo Tower started selling 10,000 tickets to its main observation deck from 9 a.m. on Tuesday.
The tickets, featuring designs marking the ceremony, are priced the same as regular tickets. Many visitors purchased them, with some saying they made the trip just to get the souvenirs.
Visitors to the 150-meter-high deck were enjoying the view of the capital under rainy skies.
A man in his 60s said he wants people to use the national holiday to celebrate the enthronement and think about the preciousness of peace.
Osaka Metro is also selling commemorative tickets. More than 100 people waited in line early on Tuesday morning at a special sales booth set up at Shin-Osaka Station on the subway Midosuji Line.
The 9-by-20-centimeter ticket features phoenixes, chrysanthemum flowers and other images. One set contains five tickets. A total of 5,000 sets were on offer.
A sixth-grader says he will put his set on display in his bedroom.
People in Dazaifu City in Fukuoka Prefecture, western Japan, are also in a festive mood. The city is associated with an ancient poem from which the name of Japan's new era, Reiwa, was taken.
West Japan Railway added a supplementary name, "Reiwa no Sato," to its Tofuro-mae Station, which is close to the Sakamoto Hachimangu shrine.
The railway unveiled a new name plate for the station in a ceremony on Tuesday.
The design features images from Japan's oldest poetry anthology, which inspired the name Reiwa.
