The Tama region, located in the western part of Tokyo, is an area rich in nature with primeval beech forests and clear streams, despite being right next to a metropolis. With good access from the city center, it is popular as a familiar hiking spot in the Kanto suburbs where people can easily experience nature.

The "Tokyo Tama Hike Stamp Rally" allows participants to explore the nature of the Tama area through two courses: the "Tama 10 Panorama Course," which visits 10 low mountains with beautiful summit views, and the "Nishitama Hills Trail Course," where you can enjoy Tama's nature more casually. The charm of both courses is that you can enjoy various expressions depending on the season you visit, such as fresh greenery, autumn leaves, and spring flowers.

When you collect stamps, you can receive a commemorative can badge and apply for a special pin badge lottery. With the extension of the event period, the production of novelty items has also been decided. Please collect the stamps and apply.
