This video report from NHK WORLD discusses several aspects of the impact of the eruption. I'd like to add one little bit of information regarding the fireworks-like image you see in the image associated with the report. I heard on another NHK broadcast that the fiery explosion you see occurred outside of the crater, near a cable-car tower, when a large mass of material from the volcano landed there. It's my impression from watching the video that the NHK camera began filming automatically after the eruption had already started. You can see hot material elsewhere, presumably from similar bombs of volcanic material that had landed earlier.

One of several eruption-related problems this article mentions is the lost of electrical power:
"Also, around 27,000 residences in Kumamoto and Oita prefectures suffered a brief power outage, which was believed to have been caused by falling ash."

An eruption at Mt. Aso in Kumamoto Prefecture early Saturday morning was likely a phreatic eruption, in which underground water in the volcano was heated by magma to cause an explosion, a volcanic expert said.

As far as I know, no one was hurt as a result of the eruption. It's probably a good thing that it occurred in the middle of the night, when tourists were not nearby and people were mostly in their homes. Aside from worry about the possibility of more eruptions, the main problem for people in the area seems to be the heavy coating of volcanic ash that they found over everything this morning. People need to be careful when they wash cars because the ash contains abrasive material. One woman interviewed said that she was just trying to avoid damage to her car by merely spraying water on it without wiping.
I also saw a report about a window that had be broken by small rocks from the eruption.

Here's the Guardian's take on the eruption. It is rather understated. For example, it says that the volcano belched "a column of ash several thousand feet into the air" when several miles or kilometers would have been closer to what NHK reported -- 11,000 meters.

As William just posted, Aso erupted early this morning. I've added English captions to the video. If you don't see them, click on the gear to select them. Here's the text:
"As we have been reporting, early this morning an explosive eruption of Mt. Aso's Nakadake No. 1 crater occurred.
According to satellite observations, the volcanic plume rose 11,000 meters.
As a result, the alert level has been raised from 2 to 3 and people have been warned of the danger of falling rocks within 2 kilometers of the volcano.
This is the first explosive eruption of Mt. Aso since 1980, 36 years ago."

Mt. Aso burped at 1:46 this morning which, according to JMA, rose to an altitude of 11,000 meters; however, it does not seem to be a precursor to anything more serious. Emissions erupted from the Nakadake #1 crater for the first time since 1980. In response, authorities have ratcheted up the warning from 2 (stay away from the crater!) to 3 (let's not even think about approaching the peak!)
Ash falls caused power outages in various locations, and JMA warns of projectiles hurled up to one kilometer from the crater. (Note: much further than I have ever hurled.) A different crater on Aso acted up on 9/14 last year, and then everything went back to normal - well, at least until April. If you're in the city, find a good vantage point for some photographs! The Mt. Kinpo peak and areas to the north of Mt. Tatsuda are recommended. - William

Kitaoka Shizen Kouen, the burial site of the Hosogawa lords since it was founded by the first Hosokawa lord of Kumamoto, Tadatoshi, was bequeathed by the Hosokawa estate to the city in 1955. In addition to several tombs, it includes many architectural features unique to the early-Edo era, in particular, the karamon (唐門, a type of gate based on Chinese architecture, 唐 meaning "China"; the article notes that there are no records of the gate having toppled since its construction). Closed since the quakes, it reopened on 10/6, though some areas remain inaccessible. Complete restoration is expected to take three years.
The area is a gem, particularly in the fall. The hill is just before Hanaoka-yama, with best access from either the streetcar Gofukumachi or Gionbashi stops. Admission is free for the time being. The area is wonderful for photography and also for shinkansen-spotting. - William

"Excessive smartphone discounts still continue" is a strange title. One might wonder "How can discounts be excessive?" But the point is that carriers are trying to entice people into accepting contracts on which that will lose money in the long term.
"The ministry implemented the guideline because it thought the continuously high communication fees put a heavy burden on household finances."
This not a Kumamoto-specific issue but, on the other hand, most of us need some kind of mobile communication so it's definitely relevant to life here in Kumamoto.
