June 2025 is turning out to be a dream month for skywatchers in Japan and around the world. From an unusually low-hanging full moon to dazzling planet-moon pairings, the skies this month are full of rare and beautiful moments. Whether you’re a seasoned stargazer or just love catching a glimpse of something magical above, here’s everything you need to know.
🍓 Strawberry Moon : June 11
The June full moon, known as the Strawberry Moon, reached its peak on June 11, and it wasn’t just any full moon, it was the lowest full moon in 18 years.
Why does that matter?
Because when the moon is lower in the sky, it appears larger, redder, and more dramatic. This “moon illusion” created stunning views during moonrise and moonset especially over Japan’s coastal or mountainous horizons.
🌑 New Moon : June 25
On June 25, the moon will completely disappear from the night sky. This New Moon is the best time to enjoy stargazing and spot constellations, the Milky Way, and even faint shooting stars. It’s also perfect for astrophotography if you’re planning a quiet trip to the countryside or mountains.
🌙 Moon & Planet Pairings (June 19–29)
June is full of magical conjunctions, where the Moon gets close to bright planets. Here are the highlights:
☄️ June 19–23 : Pre-Dawn Planet Parade
Look east before sunrise to catch the waning crescent Moon aligning with:
- Saturn
- Neptune (binoculars needed)
- Uranus
- The Pleiades star cluster
These quiet moments just before dawn offer some of the most peaceful and inspiring sky views of the year.
🪐 June 25 – Crescent Moon Meets Mercury
Just after sunset, look west to spot a tiny sliver of the Moon shining near Mercury—a rare and beautiful sight.
🔴 June 29 – Moon Meets Mars
On the last weekend of June, look to the western sky after sunset to see the Moon and Mars close together. It’s a great opportunity for photos, especially during twilight.
☀️ Bonus Highlight: Summer Solstice – June 21
The longest day of the year arrives on June 21. In Japan, this marks the official start of summer and is a great day to enjoy both sunrise and sunset views. Pair it with a night of stargazing for a full-day sky celebration!
📍 Where to Watch in Japan
For the best sky views, head away from city lights. Some top stargazing spots include:
- Nagano’s highlands
- Aso-Kuju National Park (Kyushu)
- Mount Fuji’s 5th Station (if open)
- Okinawa’s remote islands
🧭 Moon Watching Tips
- Use an app like Stellarium or Sky Guide to find exact positions of the Moon and planets.
- Bring binoculars for a closer look.
- If you’re taking photos, use a tripod and adjust exposure settings manually.
- Pack a blanket or mat and enjoy the view with some snacks and music.
The skies above Japan this June are full of rare alignments, natural beauty, and serene moments. Whether you’re watching from a mountain top, your balcony, or the beach, don’t miss the chance to connect with the cosmos.
Stay curious, look up, and let the universe surprise you!
