Kamakura's Other Hydrangea Temple

A Flower That Is Better in Bad Weather Hydrangeas are one of the few garden subjects genuinely improved by rain. The flower head is a broad cluster of flat florets that holds water rather than shedding it, so a light rain leaves the whole mass beaded and luminous in a way a dry day simply does not produce. The leaves darken, the colours saturate, and the greys of a wet temple roof behind them stop competing with the flowers.

This is why the Japanese viewing season is deliberately scheduled inside the rainy season rather than around it. Tsuyu, the front that parks over the archipelago from roughly early June into July, is the least popular travel window of the Japanese year for foreign visitors. That is the entire opportunity: the same gardens, the same flowers, a fraction of the people.

Why Temples in Particular Hydrangeas turn up at Buddhist temples far more than at shrines or public parks, and there are two reasons. The practical one is horticultural — the plant wants shade, moisture-retentive soil and shelter from hard afternoon sun, which describes the north side of a temple hall almost exactly. Temple gardens are full of the marginal, shaded, slightly damp positions where most flowering plants sulk and hydrangeas thrive.

The second reason is associative. The plant is tied to Buddhist observance through the sweet hydrangea tea, amacha, poured over the figure of the infant Buddha at Hanamatsuri in April. Once a plant has a ritual attachment it tends to be planted where the ritual happens, and centuries of that add up to the ajisai gardens temples now advertise.

The Soil Chemistry Behind the Colour The colour range is not a matter of variety alone. In most hydrangeas the flower colour responds to soil acidity — acidic soil frees up aluminium for the plant to take up and produces blues, alkaline soil locks it away and produces pinks, and the ground in between gives you the mauves and the plants that carry both colours on the same shrub.

This is worth knowing because it explains what you are seeing. A garden that reads as uniformly, spectacularly blue is usually a garden on acidic ground, which much of Japan has. A single temple showing blues on one slope and pinks on another is not showing you two collections; it is showing you its own geology.

Where the Crowds Are Not The famous temple is famous because a nickname stuck, not because its display is meaningfully better. Hase-dera, also in Kamakura, has a substantial hillside ajisai path with a sea view thrown in, and it absorbs crowds better because the route is a circuit rather than a bottleneck. Move one prefecture out from Tokyo in any direction and the calculus improves again — the temples that hold June ajisai festivals in Chiba, Shizuoka and the Kansai hills are visited almost entirely by people who live nearby.

The most reliable method is not a list at all. Ask at your accommodation which local temple people go to in June. Ajisai is common enough, and locally known enough, that this question almost always produces an answer, and the answer is almost never a place with a queue.

Going Out in the Rain Properly The practical obstacle is not the flowers, it is you. Japanese rainy season rain is warm and persistent rather than dramatic, and a day of it is comfortable with the right kit and miserable without. An umbrella beats a rain jacket in most temple gardens, because paths are narrow and you will be stopping constantly. Shoes are the real decision: temple grounds mean gravel, moss and stone steps that get genuinely slick.

One courtesy worth knowing — most temple buildings expect you to leave the umbrella at the entrance, and most provide a stand or a bag for it. Dripping through a hall on tatami is one of the few things that will actually earn you a word.
