Our Sustainable Journey
At Hotel Niwa Tokyo, we have established a unique recycling system called the 'eco-Niwa' project, aimed at environmental protection and biodiversity. We carry out various activities with the cooperation of our guests.
The logo symbolizes the concept of a 'recycling system within the hotel' by illustrating the word 'eco' as a line that spirals in a continuous loop.

Container Gardening
From Leaves to Harvest
We recycle fallen leaves collected from the four gardens within the hotel into compost and use discarded materials such as suitcases left by guests to grow vegetables and herbs on the hotel's rooftop. These fresh harvests can be enjoyed at the hotel's restaurants.
*Please note that the availability of rooftop-grown vegetables at the restaurant is irregular due to the influence of harvest periods.

Niwa Honey
A Gift from the Urban Oasis
To assist with the pollination of fruit and vegetable plants in our rooftop garden, Hotel Niwa began beekeeping in a corner of the rooftop in February 2024. The hotel is surrounded by many green spaces such as the Imperial Palace, Koishikawa Korakuen Gardens, Koishikawa Botanical Garden, and Ueno Park, allowing the bees to collect high-quality honey. The harvested honey is offered in our restaurants (for breakfast and original drinks) and is also available for purchase in jars at the front desk. (Note: Jarred honey is available in limited quantities and will be sold on a first-come, first-served basis.)
