When our prominent local host found out we were coming to Hagi, he initially thought to host us at his home, but since it turned out that there were going to be several others joining us, he made a call to his connections at one of the top ryokans in town to get us a room. It turned out that they were full for the peak fall season, but his connection at the ryokan got was soon able to get us in with the first cancellation. The evening activities were at
Hagi Honjin Ryokan, considered one of the better ryokans in Hagi. Hagi Honjin is located high up looking over Hagi, and they have three onsens (hot spring baths). The rotemburo (or outdoor bath) is accessed by a tram you take to the top of the mountain. Unfortunately, we didn't have enough time between check-in, greetings and dinner to get to the outdoor bath, but I understand it's pretty spectacular.
The dinner at Hagi Honjin may have been one of the best meals I've had in Japan. Although it wasn't high on creativity, the quality of ingredients and the cooking techniques were topnotch. We basically had one of the higher-end kaiseki menu, featuring many fall ingredients.
Here's the setup of the banquet.

The first set of courses were already laid out for us.

Clockwise from the top, we have a nabe (hotpot) with whale meat, a sashimi course, a fugu sashimi course, the main appetizer plate (with a fig in a sweet jelly sauce, a persimmon salad, a roasted and slightly braised chestnut, gingko nuts, an apple napoleon-type concoction, shrimp and egg custard roll, I think that last thing is eel, but I can't recall), miso soup, and a cook-it-yourself beef course.
A couple close-ups:


As you can see, the sashimi was pretty basic, but it was pristine. That uni, which had a darker hue than I'm accustomed to seeing was so sweet, and that squid was silky and so nicely textured. The main appetizer plate was just so interesting. That fig dish was so unexpected and wonderful. I probably could have just eaten it for dessert, but it was a nice counterpoint to the other salty flavors. And that serving of the apple napoleon topped with gold foil was also intriguing. I'm trying to recall what was in the middle of that sandwich, but the sweet and savory were a real good match in that particular dish. Beneath the persimmon slices was a mayonnaise-y salad with some seafood (again, can't recall the details), which I enjoyed. I love chestnuts, and this was also interesting with the added dimension of being simmered with a sweetened soy-type seasoning.
The beef dish was stunningly good. The beef they use is a local beef and is only available during a few weeks in the fall when a few are chosen for slaughter. From the way it was described to me, it seems like it's more prized than wagyu (kobe) beef. They were very instructive to make sure we eat it medium-rare, though I just ate it after just searing the outside, and my god, it was as tender as a good piece of ootoro.
Speaking of ootoro, it was a offered as a little mid-course:

The nabe with the whale meat was probably my least favorite item of the bunch, but it was well worth trying, but I think I'm beginning to realize that I'm just not much of a whale meat fan. It's very chewy with the blubber, and kind of livery in taste. Here's a shot of it:

While these courses alone were enough to sate me, they also offered a fish nabe course. I think it was some kind of codfish, though can't be certain. I managed to eat just a few bites.

By this time, several rounds of beer and sake went around and the group was boisterous. We had a karaoke setup as well, and that was being put into good use. Having had time to digest and work off some of those calories, I had just enough room to savor the last savory course that came around. This was takikomi gohan with matsutake mushrooms and uni. The matsutake was cooked with the rice and the uni was mixed in just before serving. It was simple and perfect.

The final final course was dessert. And it took a little while before working the appetite for it after the uni-gohan, but I'm glad I waited.

Looks pretty much like fruit, and it was. Except that one with the sauce all over the bottom was fantastic. It's nashi, or Japanese pears, which had been jello-fied somehow. I'm still trying to figure out how they did that. It had that intense sweet and slightly grainy texture like pear, but it was wobbly like jello. I think they must have pureed it and reconstituted it with gelatin. But with that vanilla cream sauce, it was a perfect end to an extravagent meal. And those pieces of persimmon and kiwi were quite nice too.
