A major game update was due at 5 p.m. A tedious bicycle task had already been outsourced, and the simulator was still waiting for new data. So I went to eat oden. On the way, a kid who looked about fifth-grade age rolled past on a kick scooter. Summer, late afternoon, scooter, game-update countdown. The mental anime title wrote itself: “Are Kick-Scooter Elementary Schoolers Only Available During Summer Vacation?” The protagonist’s goal, however, was oden.
1. A well-rated self-service udon shop
The destination was Sanukiji in Toyokawa. Public listings describe it as an udon-and-oden restaurant with a self-service format. At retrieval time, map business data showed 4.2/5 from 285 reviews, while Yahoo! Maps showed 3.93/5 from 37 reviews.[R1][R2][R3]
I asked: “Can I just eat oden?” Yes. Mission one cleared: enter an udon shop and order no udon.
2. Total self-service, plus a human tutorial NPC
A first-time visitor still has to learn what to take, where to go and when to pay. My mobile payment slowed down because of the connection, so the older staff member stepped in: “Do this, then this.” Somehow the conversation expanded into mobile carriers and smartphone networks.
In an “all self-service” shop, I talked to a human more than I might in a normal full-service restaurant. He had become the resident tutorial NPC.
3. Oden is basically a flavor-penetration game
My first verdict was “pretty good.” Then I ate the daikon: “Oh, the daikon is really good.” Oden depends heavily on how well broth penetrates the ingredient.
My personal tier list was S: daikon, A–S: hanpen, B: egg, B: konjac. Kibun’s surveys also show daikon as a dominant standard ingredient, while its texture testing describes white hanpen as soft and easy to bite through.[R6][R7]
4. Broth so good you start making bad summer decisions
The broth was good enough to inspire: “Can I put this in a thermos?” Then reality returned. It is summer. Hot outside, hot inside the thermos, hot human in the middle. This becomes “Is Your Order a Burn Injury?”
5. Prepayment weakens impulse additions
Once payment is done, adding another item means re-entering the ordering and payment flow. A ¥300 extra can feel as if it carries ¥500 worth of friction. So the backup plan became takeout dumplings from another restaurant. Except that restaurant takes phone reservations, and I was still sitting inside this restaurant.
6. Final boss: where do the dishes go?
Meal finished. I could not see a clear dish-return sign. For a moment I wondered whether this was the one part that was not self-service. I asked: “Where should I put these?” “Here.”
I looked. It was right there. There just was not an obvious label. Perfect ending: the tutorial NPC also resolved the final state.
7. Other newcomers reacted too
A nearby couple around the same generation also reacted with something like, “Oh, there’s a self-service option?” If multiple newcomers have to discover the rules, the system has an onboarding cost. That does not mean the restaurant is bad; its ratings are strong.[R1][R2]
Regular customer: fast. First-time customer: tutorial. Second visit: speedrun.
8. This is exactly the same problem as “I automate because manual work is annoying”
Self-service means work once done by staff → shifted to the customer. Automation means work once done by a human → shifted to a system.
Simply moving work is not enough. If someone still has to explain every step, handle every exception, restart every failure and tell you where the process ends, you have semi-automation with a human tutorial NPC.
Research on self-service technology links satisfaction to ease of use, perceived control, reliability and convenience. Other research describes technology paradoxes: systems can create freedom and control while also creating confusion or new tasks.[R4][R5]
9. Good self-service and good automation need the same things
- The next action should be obvious.
- Humans should handle exceptions, not routine steps.
- Adding or repeating a task should be easy.
- The end state should be clear.
- Test with newcomers, not only experts.
10. Conclusion
Wait for the 5 p.m. update. Outsource an annoying errand. See a summer-vacation scooter kid. Go to an udon shop. Eat only oden. Discover daikon is overpowered. Confirm hanpen is strong. Get help with mobile payment. Discuss carrier networks. Fail to find the dish-return sign. Ask the tutorial NPC. Discover it was right there, just unlabeled.
Moving work to someone or something else is not enough. A process becomes genuinely convenient only when guidance, exceptions and the end condition are designed too.
Also: the daikon was excellent. Oden-den-den-den.
