The spacious Japanese garden at Shirokanedai's Happo-en stays open until 9pm during the autumn foliage season. The 100 fiery red momiji maple trees are lit up during evening hours and are reflected on the surface of the garden pond. On Fridays, Saturdays and Sundays, you can admire the beautiful view while sipping on cocktails (from ¥500) that are sold at the on-site Garden Bar near the waterfall.
Make sure to also mark November 23 in your calendar – that's when you can enjoy the tunes of DJ Shuya Okino in the beautiful autumnal landscape. The event starts at 6pm at the garden’s main building and tickets can be purchased online in advance (from ¥1,500).
Between December 9 to 11, you can also enter the garden of Happo-en’s Japanese restaurant Kochuan, which is decked out with illuminations resembling moonlight. The entry fee of ¥4,000 includes one cocktail and a box of five seasonal onigiri. Reservations to visit the restaurant’s outdoor Moon Bar can be made from November 18. See the website for more information.
